I don't like how how he's been rated for us.
First of all, his close control is not that neat at all. It is not crappy, but not good enough to warrant DA 85. He's like a 80-81, no more. In fact, there are two other aspects which make him a bit harder to face him on the ball: BB and DS.
Let me explain them in detail.
BB: He's obviously stronger and sturdier than BB 75. It is actually a huge asset of him, and he uses it a lot to stand pressure and opposition while on the ball. His dribbling style is quite similar to Memphis Depay when using BB on the ball to his favour. McClean is not a heavy player at all, but he's quite efficient for the use of his body frame while dribbling. BB/Physical Contact are more like 82-83 material. Body Control more like 78-79.
DS: Taking into account that TS 82 is spot on, his DS at 78 is massively underrated. He's capable of keeping a quite reasonable amount of pace on the ball. If he has enough space, his sprints on the ball show his ability to preserve some speed while dribbling. It is mostly decent close control or some punting forward, but DS is easily an 85. It has been like that since a long time. That goal he scored against Uruguay is a great example: He got rid of Coates easily mainly after a good TS/DS combo display, without an exceptional DA.
Shoot Power: That's one hard to rate on him. I'm sure I've seen shots of him worth of mid 80s SP values, but he doesn't perform them so often. It is probably higher than 80 overall, but I'm not sure to which extent.
