Manchester United boss Ole Gunnar Solskjaer admits they've a tough task ahead if they're to progress to the Europa League quarter-finals.
United conceded a 92nd-minute equaliser in being held to a 1-1 draw by AC Milan in the first leg of their last-16 tie.
Teenager Amad Diallo's first goal for the club had given the hosts a lead but Simon Kjaer's late header levelled the game at Old Trafford.
"It makes it harder but it makes us have to go down there and score goals and win the game," the Norwegian coach said after the game.
"That might suit us. It probably will suit us. We're a team that's better when we go forward, more direct.
"Today we didn't win the ball well enough or in good enough positions to find the counter attacks.
"We were too slow, we didn't move our feet well enough in our half and they played well, to be fair, as well.
Solskjaer feels his team could have defended better for Milan's late goal.
"We dropped too deep in the box so the structure, there's a yard or two deep from everyone, really.
"Of course you're always disappointed when you concede a goal in that manner.
"Simon Kjaer is obviously a good player, he makes a good run, he's strong and his marker gets blocked off, so he gets in front of him.
"Disappointed but then again that can happen. I've been part of a team that's scored in injury time in Europe myself on a set-play.
"We know we have to travel there and score a goal and win the game, or score two and draw.
"Of course it makes it more difficult. Always when you concede at home, you're never happy when you do.
"One minute before full time is also disappointing but we've got to take that on the chin and just travel down there next week and go for it."
