London: Ole Gunnar Solskjaer says Manchester United need to harness the spirit of Paris Saint-Germain and put in a "perfect performance" if they are to overcome Manchester City and reach the League Cup final. United face an uphill battle after losing the first leg of their semi-final against Pep Guardiola's men 3-1 at Old Trafford.

Marcus Rashford's goal gives United a glimmer of hope heading to the Etihad Stadium on Wednesday and Solskjaer said the stunning comeback win against PSG in the Champions League last March can be an inspiration. United were 2-0 down after the first leg and then 3-1 down on aggregate in Paris before storming back to win on away goals. "Well, it looked like it was over at half-time," he said, referring to the first leg of the City match. "I have to say the second part of that first half, they outplayed us for a while and it's hard. "But then when we got the goal, of course you're back in it, we hope for another one.
