He won't quit. He never quits. That is something Newcastle United fans should remember as another storm starts to blow around Rafa Benitez.

It should have been a week of celebration on Tyneside, the club having secured an immediate return to the Premier League, but instead a group of supporters who have so often had to endure disappointment find themselves confused by the uncertainty that has followed.

Benitez has indicated he will only stay on at St James' Park next season if he feels that Mike Ashley, Newcastle's owner, shares his vision for what is needed to be successful back in the top flight but he is confident that 'everything will be fine'.

Watching the episode unfold brought some memories flooding back. Everything I've seen and read in the last few days had me thinking of many things, from our time together at Liverpool. He had three different sets of people to answer to at Anfield and fell out with them all.

Rafa is an excellent manager and one of the biggest influences on my career — perhaps the biggest in terms of actually being on a pitch. I played my best football under him and many of the things he taught me I still bring in to practice, whether it is on these pages or with Sky.

But he is, without doubt, the most political figure I've come across in football. I saw what is going on at Newcastle happen at Liverpool. It happened at Valencia, too, where he famously said he 'asked for a sofa and they gave me a table leg' during a row over transfers.

This posturing has a purpose. Benitez wants the maximum amount of money he can get ahead of the transfer window in order to keep Newcastle competitive. If he doesn't get the funding that he feels is necessary and next season goes badly, he can turn around and say: 'I told you so.'

BENITEZ'S CAREER 1993–1995: Real Madrid B 1995–1996: Real Valladolid 1996: Osasuna 1997–1999: Extremadura 2000–2001: Tenerife 2001–2004: Valencia 2004–2010: Liverpool 2010: Internazionale 2012–2013: Chelsea (interim) 2013–2015: Napoli 2015–2016: Real Madrid 2016–present: Newcastle United Advertisement

He raised the prospect of leaving Liverpool many times, suggesting he could go to Real Madrid, Juventus, Bayern Munich and even England! He seems almost as popular in Newcastle as he was at Anfield. He aligns himself with the fans and they are hard people to walk out on.

I'm sure the soundbites will continue and the sense of drama will heighten but this is part of the Benitez package. People talk about managers having certain styles and philosophies... well, Benitez manages by conflict. Look right through his career and you will see it everywhere.

From his time coaching the youth team at Real Madrid, where he clashed with director Jorge Valdano over the selection of certain players, conflict has followed him. At Liverpool and Valencia, that method brought him great success.

Conflict seems to follow Benitez around but Newcastle is the right club for him at the moment

At Inter Milan and Real Madrid, however, it led to him getting sacked. Sometimes he will win the battles and get the things that he wants but it doesn't always lead to him winning the war and it is an approach that puts a strain on relationships with owners, chief executives and players.

I'll come back to the issue of being sacked in a minute but, for a moment, there is one critical question that needs to be answered, when you think about the possibility of him resigning: where exactly is he going to go?

What job in the Premier League outside the elite is bigger than Newcastle? At this moment, I find it difficult to see any of the top six clubs taking him. So what else is out there? Maybe West Ham if Slaven Bilic were to leave. But would that represent a bigger step up than Tyneside? No. He is working at a club with a brilliant stadium and a huge fan base that has potential. He is also being handsomely rewarded for it.

This, though, is a dangerous game he is playing. Ashley has been subjected to huge amounts of criticism during his period of ownership but if he feels Benitez oversteps the mark, have no doubt that he will fire him.

Why wouldn't he? Ashley wasn't afraid to axe club legends and local heroes Kevin Keegan and Alan Shearer, so why would he think twice about pulling the trigger on Benitez? You don't amass the business portfolio and personal fortune Ashley has by shying away from big decisions.

Newcastle fans don't like Ashley. There have been disastrous appointments, such as Dennis Wise and Joe Kinnear and a fiasco with the renaming of the stadium but he isn't bothered about being popular with them.

So if Benitez continues to challenge him through the Press — there was an episode in January, remember, when he never got his wish to sign Andros Townsend — you could see it ending only one way: with Ashley deciding enough is enough and Rafa getting sacked.

Yet the thing is they both need each other right now. Rafa is back working in the Premier League, the domestic competition he loves more than any other, and Ashley has a manager who represents his best chance of winning a trophy.

Newcastle fans don't like Ashley, and he has made some disastrous appointments in the past

It should not be forgotten that there are few better managers in world football than Benitez in preparing a team tactically for a one-off game and there is no reason why Newcastle cannot win, for instance, the League Cup under him.

Ashley, ridiculously, has never regarded cup competitions as being important to Newcastle even though they haven't won anything domestically since 1955 but Benitez excels in them and — with the exception of Real Madrid — has won silverware at every club he has managed since Valencia, including Napoli and Chelsea.

He has met his target for the year, which was to secure promotion for Newcastle, but that was to be expected, given the money they laid out last summer to buy players such as Matt Ritchie from Bournemouth.

But the thing with Rafa is he always wants more. And that is why the agenda that has been set this week, from talk of ambition and transfers and net spends, will continue until the day this chapter in his career reaches an end.

The thing with Benitez is that he always wants more, and he will be keen to spend big this year

Don't write off old master Mourinho

So the Manchester derby ended in stalemate and though it wasn't a classic, it has set up a fascinating end to the campaign.

The theory goes that because United have trips to Arsenal and Tottenham in the next couple of weeks, the hardest run-in, they will falter. In actual fact, they have got the best manager in the business to get a result at those venues.

Jose Mourinho has had six 0-0 draws away to the top six since he returned to English football in 2013 and knows how to throw a blanket over the tightest contest.

You can bet, for certain, he will do something similar at the Emirates and White Hart Lane to what he did at the Etihad Stadium.

United will need to win one of those games. But they are very much in the fight for the top four and anyone who thinks that a couple of tough away trips will see them fail to last the distance is not looking at the whole picture.

Jose Mourinho is the master of getting results when he needs to - don't write Man United off

Man of the week - Lionel Messi

This week's column could not pass without me acknowledging the genius of Barcelona's mesmerising No 10, who continues to rewrite the record books.

There could not have been a more dramatically appropriate way to score his 500th club goal than with the last kick of last week's Clasico, his strike blowing the race for La Liga wide open and leaving his bitter rival Cristiano Ronaldo devastated.

Messi was feted in the Nou Camp on Wednesday, with a gigantic banner unfurled before kick-off in his honour. He left the field after scoring another two goals against Osasuna with a standing ovation and the crowd singing his name like a hymn.

And to think some people have suggested his form this season hasn't been what it should be. He's got 49 goals now! I've said it before but I will say it again: he is the greatest club player of all time. Let's enjoy him while we can.
