Paul Pogba, Eric Bailly, Chris Smalling and Phil Jones all trained with their Manchester United team-mates ahead of Thursday's Europa League clash against Celta Vigo.
"Let's hope Old Trafford want us to win because when Old Trafford wants it, we win".
'It's a short result, it could have been better [against Celta],' he said.
"We are always confident but it's still a semifinal and anything can happen". It's possible that Alvarez was expecting the left footed Daily Blind to take the free kick and the Celta keeper was slightly out of position as the youngster's effort went in at the far post.
Marcus Rashford is one player who picked up a knock in the Europa League.
Meanwhile, Marouane Fellaini admitted he had to "control himself" after picking up an early booking against Celta Vigo just a week after seeing red in the Manchester derby.More news: NEW YORK (CNNMoney) - United CEO Oscar Munoz's latest apology was to Congress.
United have been plagued with injuries in recent weeks and their Premier League campaign took a disappointing hit on Sunday when they were held to a 1-1 draw with relegation-battling Swansea.
"We know we can do it". If Celta was playing with their best team, if Celta was fighting for important things in La LIga, we would go in the same circumstances, but I can not now play with the same team that played in Vigo and then repeat again next Thursday.
United's Spanish midfielder Ander Herrera, who hails from the northern Basque region of Bilbao, urged caution though and stressed that Vigo remain a unsafe side ahead of the second leg. "I'm very happy and looking forward to helping the team in such an important moment of the year".
"We can not give the club the Premier League". "And it would be great to close the circle and say, "We are a club that won every single competition in the football world".
"The identity is about a lot of possession, a lot of pressure and a desire to win the ball back quickly when we lose it". "Before that, we play Southampton away a few days before, so we would be playing the final with disastrous consequences", he added. The United boss will be without several of his first team players with some of them ruled out for the season; Zlatan Ibrahimovic, Marcos Rojo, and Luke Shaw are in that category.
