The ex-Liverpool centre back was left shocked at Pogba’s desire to continuously push further up the pitch and abandon Marouane Fellaini against Pep Guardiola’s side.
In fact, Carragher was so critical of the France international’s performance that he said it made him feel sorry for Fellaini as he helplessly tried to take command of the middle of the park.
Speaking on Monday Night Football, Carragher said: “All weekend we lauded Pep Guardiola but he didn’t do anything too different to what he’s done in the first few games.
“Two wingers really wide, [David] Silva and [Kevin] De Bruyne the key players in the system, which is what they’ve been doing all season.
“I think it wasn’t Pep Guardiola that got it right. It was [Jose] Mourinho that got it wrong.”
The ex-England international then let rip at Pogba, who was re-signed by United for a world record £90 million.
“The performance of Paul Pogba: It was ill-disciplined. He was like a kid in the schoolyard, running where he wants and doing what he wants.
“I felt so sorry for Marouane Fellaini. The space in the centre of that pitch and he was left on his own by Pogba.
“He’s either got it wrong or Jose Mourinho’s given him licence to get forward.”
Was Mourinho wrong to allow Pogba the freedom of the park?
Or was it simply down to the player being keen to impress after commanding such a large transfer fee?
