Manchester United are through to the knockout stage of the Champions League but they didn’t make it look easy.The Red Devils required a late winner from Marouane Fellaini to seal a 1-0 win against Young Boys in what was another dull display.The result only served to paper over the cracks that are affecting Man United right now.They won’t last much longer in the competition playing this sort of football.Indeed, Paul Scholes felt that United would have lost if they were playing against a better team than Young Boys.“I thought they were awful tonight," he said on BT Sport. "I thought they were terrible, second half especially."I think if they play against a half decent team there, they get beat tonight.”

Scholes wasn't happy

It wasn’t just the performance that frustrated Scholes, but the reaction of Mourinho’s players as they left the pitch.

Chris Smalling and David de Gea were among those seen smiling after the win - and Scholes felt they shouldn’t have done so given the display.

“What I didn’t like was the smiling coming off the pitch at the end,” the former United midfielder added. “They should realise that they were very, very lucky to get away with that.

“And I hope in the dressing room now that the manager is giving them a bit of a rollicking.”

Scholes is entitled to his opinion but his thoughts didn’t go down well with some Man United fans on Twitter, who felt that it was an unjustified shot at the players.

Fans have been crying out for a period of consistency and they will hope that this win is followed up by another against Southampton on Saturday.

But nobody can be sure just what Man United is going to show up - the one that can defeat Juventus in Turin, or the one that fails to beat Crystal Palace at home.

And that is a serious problem.
