Crystal Palace striker Jean-Philippe Mateta's move to AC Milan is in serious doubt over issues with his medical, according to multiple BBC Sport sources.

The 28-year-old France forward had additional medical tests on Monday but the Italian side are set to pull out of the £30m deal. Mateta, who Palace manager Oliver Glasner disclosed in December has been nursing a knee issue, had an initial medical examination on Sunday.

He wants to leave Selhurst Park but Palace have been unwilling to let him go without having a replacement. The Eagles have agreed a £48m deal for Wolves forward Jorgen Strand Larsen and had granted Mateta permission to have a medical in London before flying to Milan.

Nottingham Forest have also been interested in the striker and had a £35m bid rejected by Palace last weekend.
