Frenkie de Jong's move to Manchester United is in doubt, with a number of potential obstacles in the way of a deal for the Dutch international.
United agreed an initial fee of £56million for the midfielder in June, but progress has since stalled. Chelsea also remain in the hunt for the 25-year-old, who played under United boss Erik ten Hag at Ajax, but De Jong could also end up staying at current club Barcelona.
Plenty of time remains for a deal to be completed, with Premier League clubs able to add to their squads until September 1. However, with a number of issues at play, United will need to clear multiple hurdles if they want to secure a deal for one of their manager's top targets.
