Former Arsenal striker Charlie Nicholas was left unimpressed by Harry Maguire on his winning Manchester United debut last week.
The England defender was named man of the match at Old Trafford after marshaling the United back line to a clean sheet in a 4-0 rout of Chelsea on Sunday.
Nicholas wrote Sky Sports: "I thought Harry Maguire was average, he did everything that was asked of him.
"He was efficient and got about the pitch, but I don't want to hear nonsense about him being a leader and strong on the pitch already, it is too soon.
"He has started well, but I am suspect about the right-back and left-back positions at Man Utd.
"Chelsea could have easily scored two or three. I am still not convinced by Manchester United and I would still sell Paul Pogba."
