The Red Devils will head back to Old Trafford looking to build on a 1-0 advantage handed to them by Marcus Rashford's spectacular free-kick.
With Jose Mourinho's side struggling to break down a competitive Celta defence, and finding goalkeeper Sergio Alvarez in fine form, it looked as though the game may have been heading for another frustrating draw.
"Now we have a second game and we have to be ready because it will be a big game for us".
"We know we can do it", he emphasized. We take too many touches and it allows them to come back and have 10 players behind the ball when we attack and after that it is going to be very hard for us.
"We played well enough to have the result closed but we have to go and play at Old Trafford. I remember that I still met him in the corridor for the press conferences, we shook hands again". Obviously he's seen the keeper move to the left and he's created that space for himself to find the corner.
"So for me not a problem at all and I think he will be really pleased with me that I am going to change my team against Arsenal".
Daley Blind has warned his Manchester United teammates there is still work to do to secure a place in the Europa League final.
"We are always confident but it's still a semifinal and anything can happen".
But Lingard believes the way he responded with a goal against Celta Vigo shows that nothing can faze a player who has still only made 66 senior appearances. We are not going to Arsenal to say "beat us" or 'beat us 5-0 or 6-0.' We are going there to fight for a result.
"We had good chances in the first half that we didn't finish".
To add to United's concerns, Young appeared to pick up a hamstring injury during his 12 minute cameo after being introduced as a second half substitute for Henrikh Mkhitaryan.
Mourinho then threw down the gauntlet to United's support at Old Trafford for next Thursday's second leg. "Let's hope Old Trafford want us to win because when Old Trafford wants it we win", he said.
