Jesse Lingard will reportedly earn Manchester United a £500,000 bonus if he can help West Ham qualify for the Champions League.
The midfielder joined the Hammers on loan in January and has flourished under David Moyes, playing a huge role in their unlikely push for European football.
Three defeats in their last four games by Newcastle, Chelsea and Everton have dented West Ham's chances of a top-four finish but they are still six points off fourth place with a game in hand.
According to The Sun, United will pocket a £500,000 bonus if West Ham manage to squeeze into the top four as part of the loan deal they struck with the Red Devils for Lingard at the start of the year.
