Former Manchester City striker Niall Quinn says Manchester United boss Ole Gunnar Solskjaer was wrong to keep Fred on the pitch after halftime last night.

In defeat to PSG, Quinn believes Solskjaer made a huge mistake for failing to take Fred off at half-time, as he suggested his fortunate at escaping a red card for an apparent first-half head-butt should have led to his substitution.

Asked whether Solskjaer would get criticised for his decision to leave Fred on the field, Quinn responded on Virgin Sport: "Absolutely loads and deserved.

"At the very least, he must have addressed it at half-time. Can I trust you? The world and his mother knew he was walking a tightrope, so the best thing to do was get him off.

"He is wrong to even trust him. He should have whipped him off and he should have an assistant who takes him to one side and say look what will happen to you if he gets sent off. That's what's happened."
