Jose Mourinho will not be happy with how the summer transfer window went.
The Portuguese manager was chasing a centre-back throughout but he could not persuade any of his targets to join the club.
It was reported that Mourinho made a last ditch effort to buy a centre-back on transfer deadline day, with Diego Godin, Harry Maguire and Toby Alderweireld all linked to the club.
But in the end there were no new arrivals, which would have frustrated Mourinho greatly.
While Mourinho was unable to add to his squad on deadline day, there was a notable departure.
Timothy Fosu-Mensah was allowed to leave on loan to Fulham.
But how do Manchester United fans feel about letting the youngster leave?
It turns out that they were not happy at all, and a large selection of supporters raised a very good point to Mourinho.
Many fans expressed their disappointment that one of their young stars had been allowed to leave the club.
And they could not believe that Mourinho had sanctioned the move, especially as Mourinho was unable to add to his options at centre-back.
They have got a good point.
Mourinho clearly doesn't trust the centre-backs he has at his disposal.
Why he hasn't given a chance to a young and talented player, especially after failing to buy a centre-back, is baffling.
In the end he ended up with less options at the position, rather than more.
The Dutch defender spent last season on loan at Crystal Palace, where he proved he is capable of performing to a high standard in the Premier League.
Fosu-Mensah also has the ability to play at right-back, meaning he could have provided cover for Antonio Valencia once Matteo Darmian departs the club.
But Mourinho felt sending him on loan was the best decision, one that fans are not overly convinced by.
Meanwhile, Gary Neville believes that the club are two centre-backs short in their bid to become Premier League champions once again this season.
“I don’t think the centre-back pairings are good enough so I do think Jose is right,” Neville said, per independent.ie.
“They need a strong centre-back pairing. I think they have capable defenders but I’m not sure there is a great pair there.
“That’s always a problem. ‘Who’s the back four?’ I don’t know. They have signed a good right-back (Diogo Dalot) but he’s not quite fit yet.
“They did need one or two centre-backs and that worries me in terms of them winning the league. But I do think they have a great squad still but they are one or two centre-backs short.”
