McCarthy told betonlinepromocodes.com: "I couldn’t fault Jadon in training. He brings unbelievable quality, ability and skills. He can make you stop in awe and ask yourself just how he can do things. He brought unmatched quality.
"I think what didn’t help Jadon was that he’s a very closed-off person. He keeps to himself, and from the outside it looked like he wasn’t trying to make friends with his team-mates. He might not have joked around but really he was just quiet, and I don’t think you should judge players on who he gets on with or not.
"Based on his ability and craft, I never saw any problems in his relationships. He was quiet natured, and so when training is done, he doesn’t stay to talk, he heads home. He’s very private. I think a bit of an introvert, which isn’t the opinion he gets branded with in the press.
"I think that when it came to Erik, he wanted to see Jadon at his best everyday. Monday to Friday, no days off. I think that’s what the manager would expect from his players, and so it’s up to the players to give it to him. If you can’t do that, you’re going to have problems, and I think the differences and problems then surfaced.
"For me, I don’t have a bad thing to say about Jadon. I loved him, he was unbelievable, sometimes he was unplayable. I don’t want to rush to judgement on players if they’re reserved."
