The World Cup has become a high-stakes shop window for Premier League clubs, but a little-known FIFA rule change has already forced several nations into early eliminations, tightening the market for talent. With the transfer window open, BBC Sport journalists have identified key names under the microscope.
Newcastle United have not ruled out a third attempt in three years to sign England goalkeeper James Trafford from Manchester City. On the eve of England's opener against Croatia, the 24-year-old accepted he must be first choice at club level to fulfil his dream of becoming England's number one – a concession that could play in Newcastle's favour if they return for City's cup keeper.

Liverpool have shown interest in Ivory Coast winger Yan Diomande, while Manchester City continue to target England and Nottingham Forest midfielder Elliot Anderson as a key signing. Manchester United, meanwhile, may bolster their left side with a more defensive option: Fulham's Antonee Robinson, a USA regular who completed the full 90 minutes against Paraguay and 80 against Australia.
Brighton have already had a couple of bids turned down for Tottenham defender Luka Vuskovic. The 19-year-old started Croatia's World Cup opener with England in a three-man defence but was replaced 20 minutes into the second half. He was nearest to Harry Kane when the striker got a free header for his second goal and could not get beyond John Stones as he leaped to challenge.
Crystal Palace enter the season as Conference League winners and face a tougher Europa League campaign. Last season highlighted a lack of squad depth, prompting the club to bring in Jorgen Strand Larsen, Brennan Johnson and Evann Guessand in the winter window. Now, with higher competition ahead, they need to invest again. Tyrick Mitchell is the only first-team quality left-back, while right-back Daniel Munoz – at the World Cup with Colombia – had knee surgery last season and has not looked the same since.
As the tournament progresses, these clubs will be watching closely – but for some players, the chance to impress is already over.
