Arsenal legend Ian Wright says Manchester United's defence was rattled by Stoke City striker Maxim Choupo-Moting.
Choupo-Moting struck twice in the 2-2 draw with United.
"(Man Utd) have got the plaudits going forward so far this season, rightly so because they have been playing very well," said Wright, “but Stoke really tested them, especially the two centre-halves Jones and Bailly and there were times when they were really rattled.
“Stoke were brilliant, they were intensified and they were really going at them.
“When you see the first goal you think the game has stopped because look how much time Fletcher has got. Bailly doesn't react until it's too late. He ends up on his backside.
“Then before the second goal I was thinking it was a game-winning save (from David de Gea to deny Jese Rodriguez) and I was thinking oh my gosh – then from the corner I wouldn't want to see my centre-half being beaten so easily. There's no challenge.
“Choupo-Moting was brilliant. He got three goals last year at Schalke and he's already got two and not only did they come against Man Utd, he's flying, but he really was a handful.
“It made Bailly tetchy and he had the hump. At one stage he has a dig at Kurt Zouma then Xherdan Shaqiri comes in, and bang, he has a go at him, whack, he was being nuts. He had the hump."
