When Paul Pogba completed his world record switch from Juventus back to Manchester United many fans thought their prayers for a world class midfielder had been answered.
But three consecutive defeats, which have all featured gaping holes in a midfield consisting of the Frenchman, have left a fair few supporters scratching their heads.
Jose Mourinho's first choice pairing of Pogba and Marouane Fellaini were exposed against Pep Guardiola's Manchester City and Watford so now the Portuguese has been urged to tinker with his other options to find the right balance in the middle of the park.
Michael Carrick is one of those who is yet to be given an opportunity under Mourinho and one of his former central midfield partners can't understand why.
The Englishman's contract at Old Trafford was set to expire at the end of last season but Man United's new manager chose to offer him an extension to keep him at the club for another year.
So it has been surprising to see one of United's longest serving players not being given a chance, particularly when the current starters are struggling so much.
That is exactly how Paul Scholes feels and, after the Red Devils' 3-1 loss to the Hornets on Sunday, pressed Mourinho to start picking Carrick over Fellaini.
"I thought Fellaini was alright today; he does a job in there," Scholes told BT Sport. "But I think that if you are Manchester United, you need more than that.
"You need someone who can stop the play as well, someone who can stop the opposition but who is capable of controlling a game of football as well, playing forward and passing forward.
"As well as he (Fellaini) has done in the first three or four games, I just can't understand why Michael Carrick's here. It looked last year like he was leaving, he's not been involved a minute of the season, so what he's done I don't know."
Carrick has made over 400 appearances for the Red Devils and it could prove that his experience is exactly what Pogba needs to flourish in his second spell at the club.
Mourinho will have the opportunity to test a different midfield combination in the League Cup tie against Northampton this week but another defeat will prompt fans to start asking serious questions about the lack of progress made since Louis van Gaal was sacked in May.
