'This is not done' - Ruben Amorim fires out warning to Man Utd after 3-0 win over Athletic Club in first leg of Europa League semi-final

United travelled to San Mames to take on Athletic Club for the first leg of their Europa League semi-final expecting a difficult outing. However, the Red Devils cruised through Los Leones as they took a three-goal lead before half-time, with centre-back Dani Vivian was sent off controversially.

United were faultless throughout the clash at San Mames, as a goal from Casemiro followed by a brace from Bruno Fernandes helped them secure a crucial 3-0 win away from home. The two sides will lock horns next Thursday at Old Trafford, and Amorim has fired a warning to his players that the tie is not yet over despite their massive win.

Speaking to TNT Sports, Amorim said: "The result is really good, but we have to understand the result at the same time. We struggled a lot at the beginning and the sending off changed the game. Any game can change with one situation. We had an opportunity to score one more. This is not done and they can do the same at Old Trafford. They're really strong and intense. We need to be prepared. Manuel Ugarte with a lot of experience was a little nervous, Patrick [Dorgu] was nervous. Players like Casemiro, Harry Maguire, Bruno Fernandes help a lot."

Amorim has admitted that United 'have an advantage', when they host Athletic Club at Old Trafford on Thursday, May 8, as they continue their hunt to qualify for the Champions League. The Portuguese coach said: "Of course we are have an advantage. We have our fans, but again this could change. Anything can happen in one game. We need to be really careful with our players against Brentford. Noussair Mazraoui is dead, Patrick Dorgu is tried - we have to manage the players."
