Ole Gunnar Solskjaer is astute enough to realise that memories do not win matches. It is fair to assume, then, that Clive Tyldesley’s most famous commentary will not be getting an airing on the Manchester United team bus to the Nou Camp on Tuesday evening.

It will be 20 years ago next month since Solskjaer, in the same stadium, scored the United winner that completed a miraculous comeback against Bayern Munich in the Champions League final.

Turning round a one-goal deficit against Barcelona this week would arguably be a bigger achievement, given that United are not as strong a force now as they were then.

Solskjaer’s task over the next 36 hours is to work out how to do it. Rather than reach into the distant past, he will call on more recent examples of remarkable European comebacks to inspire his players.

After all, it is only six weeks since United travelled to Paris St-Germain in the last 16, trailing 2-0 from the first leg and with no one outside Old Trafford giving them a chance. They came through.
