The Spain international was recently filmed training alone on a beach in Brazil after having been left out of Chelsea’s pre-season tour squad.
‘Sky Sports News’ reports that Milan have met with Costa’s agent with Milan chairman Fassone describing the striker as ‘a great player’.
Fassone told ‘Sky Sports News’: “I would prefer to avoid talking about players from other teams; Diego Costa is a great player, but a Chelsea player.”
“We went to see Jorge Mendes; there is a lot you can talk to him about. Costa is a great player but he is of Chelsea. That’s all.”
It it believed that the meeting with Jorge Mendes may have been the same one during which a move for Real Madrid’s Cristiano Ronaldo was discussed, with the Italian giants considering a sensation swoop for the Portuguese.
Costa was Chelsea’s top scorer last season but is free to move on this summer following the arrival of Alvaro Morata.
