Crystal Palace are expected to follow the appointment of Dougie Freedman as sporting director with an offer for Oliver Burke, with the Scotland winger braced to leave RB Leipzig before the end of the transfer window.

Burke, who worked with Freedman at Nottingham Forest, moved to the Bundesliga club last summer for £13m but, despite some promising early cameos and a goal on his third appearance, made only five league starts over his debut season. The 20-year-old was omitted from the Leipzig squad for Saturday’s loss at Schalke in the first round of German top-flight fixtures, with Frank de Boer having confirmed Palace’s interest last week. He is likely to cost around £15m.

The London club, still pointless and goalless under De Boer as they adjust to the new manager’s preferred style of play, host Ipswich Town in the League Cup second round on Tuesday evening with the rejigged recruitment department working on a number of potential deals in and out of the club.

The Roma goalkeeper Lukasz Skorupski has been discussed and Palace are one of a number of Premier League clubs monitoring Munir El Haddadi’s situation at Barcelona. The 21-year-old forward spent last season on loan at Valencia and has also been discussed as a potential signing by Newcastle United.

The AEK Athens centre-half Ognjen Vranjes has also been scrutinised by Palace as a cheaper option than Mamadou Sakho of Liverpool. The latter, who enjoyed a successful loan spell at Selhurst Park last term, is available in a deal that could eventually cost £30m – albeit Liverpool appear to be shifting their stance over the size of the initial payment required to secure the France international – but Palace are intent upon complying with the Premier League’s financial fair play regulations.

The chairman, Steve Parish, has moved to secure three players to date – Jairo Riedewald from Ajax and the loanees Ruben Loftus-Cheek and Timothy Fosu-Mensah – and indicated over the weekend that he would ideally like to add at least three players to De Boer’s squad before next week’s deadline.

However, there may be departures, too, to trim a hefty wage bill. Yohan Cabaye has entered the final 12 months of his contract – Monaco, Milan and Marseille are credited with an interest in the midfielder – and Burnley are understood to be interested in signing Martin Kelly.
