Manchester United are a club with a strong history of European comebacks - as interim manager Ole Gunnar Solskjaer knows better than just about anyone.
They will need to summon a doozy of a revival on Wednesday as they take on Paris Saint-Germain in the second leg of their Champions League round of 16 clash, having lost 2-0 at Old Trafford in the first game.
The United players, and their manager, were seen arriving for training at Carrington on a sunny Monday morning ahead of their immensely tricky task.
Solskjaer is urging his players to produce another United miracle, 20 years after the side he played in created magic in order to go all the way in the 1999 Champions League.
United came from two goals down away from home in the semi-final against Juventus in Turin, before their stunning last second victory over Bayern Munich in the final.
Solskjaer's side are heavily depleted for the game - Alexis Sanchez is injured and Paul Pogba is suspended.
However Romelu Lukaku, who was among the stars pictured arriving at Carrington, has found some form, and Solskjaer feels his team have the spirit to perform a comeback.
Recalling that famous night at the Stadio delle Alpi, he added: 'Juventus scored two to go 2-0 up in the first 10 minutes and suddenly you think you're out.
'Yet as soon as we got that one goal away from home, we were in the ascendancy. When we got the score to 2-2, suddenly we were through and they had to panic.
'So that's it for us. We have to get goals in the game. If we get an early one, then suddenly we're in with a shout. We know it is going to be difficult and we've got loads of injuries, but there are a few boys who will want to be part of it.'
