Uh oh, there may be trouble ahead.
Manchester United have had a £75M bid accepted by Everton for Romelu Lukaku, according to the Telegraph.
The Telegraph report that Chelsea were previously thought to be front runners in the race to sign Lukaku, but Man United have been working hard behind the scenes in order to steal him from under the noses of their rivals.
It is reported that the Red Devils are keen to complete the deal to sign Lukaku by Sunday, leaving Chelsea out in the cold.
This is a huge concern from a Chelsea perspective, as the Telegraph revealed in a separate report, Diego Costa has already said his goodbyes to his Chelsea teammates ahead of a return to Atletico Madrid, which would leave Antonio Conte without a viable option to lead his attack.
The Telegraph do suggest that Chelsea could make a late move to sign Lukaku, but it look as though the deal to take him to Old Trafford is already too far advanced.
