Celta Vigo goalkeeper Sergio Alvarez has taken responsibility for Marcus Rashford's winner for Manchester United in the first leg of their Europa League semifinal.
United dominated Thursday's encounter at the Balaidos stadium but only won 1-0 after Rashford's free kick in the 67th minute beat Alvarez, who made four saves on the night but admits he could have done better to keep out the goal.
"It's a pity about the free kick and I'm disappointed I couldn't help my team on that play," Alvarez told Onda Cero radio. "There were two players [Rashford and Daley Blind] on the ball, a right-footer and a left-footer. I thought Blind would take it.
"I saw the ball late. I took a step to the left that I shouldn't have taken and that prevented me from getting to the ball by a few centimetres. When I reacted, it was too late."
Alvarez says he and his teammates can overcome the deficit in Manchester on Thursday and take Celta to the final in Stockholm later this month.
"We have to go there and give our all," Alvarez added. "I know this team can do it. We need to correct some mistakes.
"But we have to go there and prove that we are a brave team and that we will not give up until the end. We are going to fight to achieve something historic."
Celta's away form has been good in the Europa League this season, with 2-0 wins at Panathinaikos, Shakhtar Donetsk and Krasnodar, and just one defeat from their six games on the road.
United midfielder Ander Herrera says his team will need another dominant performance at Old Trafford.
"We can be happy with our performance but we have to be on alert," Herrera told Marca. "Celta have always scored away from home and that must mean something.
"If we want to be in the final, we know we have to play the return leg just as well as we did in Vigo.
"We are very aware that Celta eliminated [Real] Madrid from the Copa [del Rey] and we are not thinking we have sealed victory. We have a 50 percent chance of winning the tie and 25 percent chance to win the title.
"We have to respect them. The coach is not going to let us get distracted."
Winning the Europa League guarantees a spot in the Champions League next season, with United currently outside the Premier League top four.
"There's a lot at stake for us," the Spain international said. "For us, it's crucial. No one will remember what we've done if we don't win and we don't play in the Champions League next season."
