on one hand the red card was a hard blow for Bilbao so that it made their plans fall apart, but unfortunately Bilbao also had to let their goal be bombarded with three goals and that made it even more difficult for them in the competition. Manchester United were certainly very happy with the result and surprised people, because United were not favored at all in that match. Leg 2 will be easy for Amorim's troops because they already have a lot of capital and I am optimistic about their chances of advancing to the final round.
The red card received by Dani Vivian in the 33rd minute made the match lopsided, Bilbao were increasingly under pressure because they were outnumbered and had difficulty keeping up with Man United who were increasingly free to control the match. Amorim really shifted their focus to the UEL after losing hope in the Premier League, they are still the only team that is still unbeaten until the semi-finals.
The second leg is hopeless for Bilbao as it is highly unlikely they will be able to score 4 goals without reply at Old Trafford.
Vivian made a silly mistake yesterday, that's an important match a big one for that matter therefore he should've been very careful, Hodjlund is known for his goal drought and ill luck this season, if Vivian hadn't pulled him back maybe he would've missed the goal, but then his error caused his team to lose cause they got destabilised after Vivian got sent out. Yeah, Amorim made the best decision, the Europea League is a free ticket to the Champions League if they win it, and I love that the players all bought that idea and showed seriousness to win it and get a free entry to the Champions League, that's why they've been suprisenly unbeaten till this point, 3 goals at Bilbao's home is a big advantage to Manchester United, much pressure would be on Atletico Bilbao at Old Trafford.
