Manchester United manager Ole Gunnar Solskjaer has been told that the only reason for him to keep his job at the Old Trafford is for him to win trophies for the club.

According to the club legend Rio Ferdinand, Solskjaer will face the sack at Manchester United if he does not deliver trophies this season after the Red Devils lost to Young Boys on Tuesday.

Solskjaer’s side were deservedly beaten by Young Boys in their first Champions League group stage match of the season, after being dominated by the Swiss side for most of the 90 minutes.

United took the lead through Cristiano Ronaldo but Aaron Wan-Bissaka’s first-half red card changed the course of the game, with the resilient Young Boys scoring twice after half-time, including a 95-minute winner from Jesse Lingard’s mistake.

The result represented United’s first loss of the season and after suffering a Champions League exit in the group stages last season, Ferdinand has ramped up the pressure on Red Devils Solskjaer, reiterating that the Norwegian has yet to prove he is a trophy-winning manager yet.

“Of all the managers in the top-four fight, Ole hasn’t proved he can win at this level yet”, Ferdinand told BT Sport on Tuesday night.

“He’s done what he’s been asked to do up until this point. Now its D-Day.

“It’s his squad, shaped by him, a wonderful transfer window just gone, bringing in winners, people that can change the culture of this club.

“Now he’ll be judged properly. Now you’ve got to convert that to trophies and if he doesn’t his head will be on the chopping block like any other manager.”

The Red Devils are tipped to enjoy a good season after making high-profile signings such as Ronaldo, Raphael Varane and Jadon Sancho this summer.

Solskjaer’s side have enjoyed a good start to the season, claiming victories over Leeds, Wolves and Newcastle which means they currently top the Premier League.

United started their evening in Switzerland brightly when Ronaldo scored his third goal in two games since rejoining the club from Juventus last month, but matters soon turned sour in Bern.

Wan-Bissaka was dismissed for a high tackle on Young Boys’ Christopher Martins and United were second-best against their opponents from that point.

Moumi Ngamaleu got ahead of Raphael Varane with just under 25 minutes left to restore parity for the Swiss side, before Jordan Siebatcheu picked up Lingard’s poor backpass to David de Gea to seal the win in the last victory of the game.
