The Red Devils have been linked with a move for the English star as they seek a long-term replacement for Casemiro, while Kobbie Mainoo could also leave Old Trafford due to limited playing opportunities.
Wharton’s standout performances at Selhurst Park have already drawn attention from top clubs across Europe, including Real Madrid and Manchester United.
Commenting on the midfielder’s transfer speculation, the Eagles’ co-owner told talkSPORT: "I think Adam at some point will want to play either in the Champions League with us, if we can make that happen, or probably with another club.
“He's an extraordinary talent. I think right now, and I can't speak for Adam, but I think he's focused on his time at Crystal Palace. He had a broken season last season with the groin issues that he had that a lot of young players get.
"I think this season he's completely focused on putting the games in, getting in the England squad, being a regular for us, and making sure that he can show that Saturday, Sunday, Thursday, Sunday.
“It's a difficult programme for us right now. I think he's very committed to the club. I don't know where all this stuff comes from."
