Speaking on theOn The Whistle podcast, McCarthy said: "[He's] a great boy, great character, fantastic footballer, unbelievable the things that he can do. For me, it was a real shame that it didn't work out for Jadon at United, because I thought he was the type of player that that would flourish in a United shirt. But unfortunately, I think lack of communication and understanding, I think was part of the downside that didn't end up working with Sanch.
"He's closer to home because he did sneak out to come to London quite a lot. So probably the fact that he was missing home, and, just wanted to be a bit closer to to family and friends and his culture. The London culture is quite strong, so I think Jadon maybe wanted more of that. So that's why he kept on. He was in London quite a lot.
"Now he is closer to home, so hopefully he can find that peace, he can find that bit of magic that that he found when he went to Dortmund, and he gets the love that he deserves from the coaching staff, the players. I think he will turn out to be a special player again. Because I think every single one that knows Sancho that would want him to be at that level, because it's good for world football."
