Manchester United legend Gary Neville has questioned the signing of Fred.
Neville believes the Shakhtar Donetsk midfielder has failed to meet expectations since his summer arrival.
Referring to Sunday's derby defeat at Manchester City, he said, "Fred, who was signed for £60m, started the season against Leicester and you thought he looked bright and tidy, but does he look like what you expect for £60m? Does he look like he is going to change a game, defend your goal or connect back to front? At this moment in time no, but he is still developing and getting used to Manchester United and he is coming into a very difficult position as the club isn't the most stable in terms of the performance levels and the scrutiny on the club.
“I wouldn't put it all onto Fred, but it's right to ask the question where he was today when Marouane Fellaini and Ander Herrera are still there, both of whom are determined players and give their all, but it's not a lack of effort, it's a lack of quality.
“Manchester United lacked quality in central midfield. You look at Bernardo Silva and David Silva for Manchester City and every time they touch the ball it's amazing to watch. When you watch Fellaini and Herrera on the ball it's completely different."
