Jamie Redknapp has claimed that Jose Mourinho does not "have a clue" about his best starting lineup following Manchester United's 3-2 defeat at Brighton & Hove Albion on Sunday.

Mourinho made three changes to his side for the trip to the Amex Stadium as Alexis Sanchez, Marcus Rashford and Matteo Darmian all dropped out of the team to be replaced by Anthony Martial, Romelu Lukaku and Ashley Young.

The Red Devils subsequently slumped to an error-strewn defeat to the Seagulls, and Redknapp believes that the result showed how far the club have fallen since the glory days of Sir Alex Ferguson.

"What is his best XI? I don't think he has a clue what his best XI is,. The problem for Manchester United is you look at the other teams and they know exactly what they are trying to do and how they are trying to play, and I have never seen a team lacking so much desire to get back into a game," Redknapp told Sky Sports News.

"How much more money can you throw at the problem? He has bought [Victor] Lindelof and [Eric] Bailly and they looked so poor today, why would you trust him to spend more money? I played against Manchester United for many years and you always expected a comeback.

"You can lose a game but it's the manner you lose it and I don't think I have seen United lose a game like that in a long time, where they showed no appetite to get back into it. There was a lack of desire and that is a real worry for Manchester United. Jose will get criticism but the players have to take responsibility, they can't just hide behind the manager all the time. They are not putting in a shift. They have to do more."

The defeat saw United concede three goals in the first half of a Premier League game for only the 10th time.
