The Football Association will offer Gareth Southgate half of what they paid Sam Allardyce to become England manager after he takes charge of his final match as interim boss against Spain on Tuesday night, it has been revealed.

The Telegraph reports that the FA are ready to appoint Southgate on a permanent basis, regardless of the result in the international friendly against Spain, after he secured two wins and a draw from his opening three matches in charge of the senior side.

Southgate stepped up from his role with the Under-21s to replace Allardyce after he left by mutual consent following The Telegraph’s undercover investigation that caught Allardyce offering advice in how to get around FA regulations and also attempting to secure lucrative work in the Far East with reporters purporting to be investors.

However, that deal is reported to be worth £1.5m-a-year, and stands at half the £3m that Allardyce was supposed to be paid annually by the FA.

Southgate’s contract, should he agree to the terms, is significantly less than Allardyce and Roy Hodgson – who led England to an embarrassing last-16 exit at Euro 2016 this year – although there are performance-based bonuses that could see his salary enhanced.

It does though represent a significant increase on his previous wages as Under-21s manager, for which he is currently paid around £500,000-a-week. The new deal will run until the end of the 2020 European Championship, although it will also include a break clause that can be activated after the 2018 World Cup should England’s performance result in an unavoidable change.

It’s understood that Southgate is willing to agree to the break clause, although the offer has not yet been made ahead of his fourth and final match as interim manager at Wembley this evening.

England vs Scotland player ratings Show all 30 1 /30 England vs Scotland player ratings England vs Scotland player ratings ENGLAND: 15-Mike Brown Busy game, his best for a while, not least for his left-footed kicking option. Equalled Matt Perry’s record as most-capped England full-back (36). 7/10 Getty Images England vs Scotland player ratings 14-Anthony-Watson Frustrating day at the office. Did little wrong but not as involved as he should be. Still learning the Chris Ashton-style tracking skills. 6 Getty Images England vs Scotland player ratings 13-Jonathan Joseph Wonderful early try when he came short off Ford and jinked past Hogg for his fourth try of the tournament. Looked a class act once again. 7 Getty Images England vs Scotland player ratings 12-Luther Burrell Failed to trust his left-hand pass in first minute, butchering a try. Not hitting the heights of last year but offers a physical threat. AP England vs Scotland player ratings 11-Jack Nowell Relished the open spaces with ball in hand but blew a try and got sucked in too easily defensively. Still a work in progress at this level. 7 Getty Images England vs Scotland player ratings 10-George Ford Threatened Scotland throughout with his delayed passes on the gain-line. Ghosted through for valuable try soon after the break. 8 Getty Images England vs Scotland player ratings 9-Ben-Youngs Improvement from Dublin. Took more responsibility and varied his game well around fringes. Holding off Wigglesworth’s challenge. 8 Getty Images England vs Scotland player ratings 1-Joe Marler Penalised more than once at the scrum but, after 10 successive starts, has plenty of credit in the bank. 6 Getty Images England vs Scotland player ratings 2-Dylan Hartley His lineout arrows were slightly off. He remains under fierce pressure for the No 2 shirt from Tom Youngs. 5 Getty Images England vs Scotland player ratings 3-Dan Cole Lucky to avoid yellow card for his goal-line lunge at the ruck. His discipline was a bit loose but put in good shift at the scrum. 6 Getty Images England vs Scotland player ratings 4 -Dave Atwood The Bath man is always a force in the maul and scrum but still needs to do bit more around the park. 6 Getty Images England vs Scotland player ratings 5-Courtney Lawes Big impact on his first appearance since the autumn. Prominent in lineout and put constant pressure on the Scots, as Russell can testify. 8 Getty Images England vs Scotland player ratings 6-James Haskell Questionable whether he is doing enough to fend off Wood’s challenge for the No 6 shirt. His forward pass denied Brown a second-half try. 6 Getty Images England vs Scotland player ratings 7-Chris Robshaw As consistent as ever. Stuart Lancaster’s fear must be whether the skipper can keep going at full throttle until the World Cup is done. 7 Getty Images England vs Scotland player ratings 8-Billy Vunipola Scotland kept him under wraps pretty well. Like Robshaw, no doubting his engine. His power from standing start is wondrous at times. 7 Getty Images England vs Scotland player ratings SCOTLAND: 15-Stuart Hogg Saved Scotland three times with his last-ditch tackles on Burrell and Brown during the early English siege. 8 Getty Images England vs Scotland player ratings 14-Dougie Fife Will be pleased with his efforts after coming in for Sean Lamont. Did not look out of place and made crucial try-saving tackle on Nowell. 7 Getty Images England vs Scotland player ratings 13-Mark Bennett Looks set for a long spell in the No 13 shirt. The Glasgow centre took his try well and shows terrific composure for a 22-year-old. 8 Getty Images England vs Scotland player ratings 12-Matt Scott Flew out the line to provide Joseph with his fifth-minute try. First Test start for a year and looked like it. 6 Getty Images England vs Scotland player ratings 11-Tommy Seymour Forced to switch from right to left wing and coped efficiently. Honours even with his battle with Watson. 7 Getty Images England vs Scotland player ratings 10-Finn Russell Good touches though did not enjoy the close attentions of Lawes and Co. But Scots must keep the faith - he can get a back-line moving. 6 Getty Images England vs Scotland player ratings 9-Greig Laidlaw Raised the tempo when called for. The experienced No 9 is a vital presence in such a young back-line. 7 Getty Images England vs Scotland player ratings 1-Alasdair Dickinson Tends to fade in later part of the match but his lineout work is as good as at any time in his career. 5 Getty Images England vs Scotland player ratings 2-Ross Ford Tends to fade in later part of the match but his lineout work is as good as at any time in his career. 7 Getty Images England vs Scotland player ratings 3-Euan Murray Equalled Allan Jacobsen’s caps record for a Scottish prop (65). The former Lion still has plenty to offer, in the set piece at least. 7 Getty Images England vs Scotland player ratings 4-Jim Hamilton Brought in by Vern Cotter for his physicality and strength in the maul and he didn’t let his coach down. Is a more disciplined player these days. 7 Getty Images England vs Scotland player ratings 5-Jonny Gray Scotland’s captain-in-waiting according to some. A menace in the lineout and shows maturity beyond his years – he was 21. 7 Getty Images England vs Scotland player ratings 6-Robert Harley Possibly shaded the battle of the blind-sides. Likes to annoy opponents and generally succeeds. 6 Getty Images England vs Scotland player ratings 7-Blair Cowan Earning an unwanted reputation for conceding penalties, but he remains a key cog in this side. One of the best turnover merchants around. 7 Getty Images England vs Scotland player ratings 8-David Denton Gave Scotland a good ball-carrying outlet and more bulk in the tight exchanges. Decent performance before giving way to Beattie. 6 Getty Images

Allardyce was appointed earlier this year by a three-man panel made up by FA chairman Greg Clarke, chief executive Martin Glenn and director of elite development Dan Ashworth, although this time around a fourth has been added in League Managers Association chairman Howard Wilkinson.

Crowd violence mars Englands win over Scotland

Southgate has made it clear he wants the job without directly saying so, and with his attentions currently split between the senior and Under-21s given he does not know where his future lies, he has called on the FA to make the decision soon to ensure his full focus can be given to whichever team he takes charge of.
