That can't be a reference, Bilbao this season has performed quite impressively so it's not easy for Manchester United in this semifinal round even though many favor Manchester United but I don't think because of that the percentage will increase.
The first leg tonight Manchester United will play away which of course makes it even more difficult for them but if Manchester United plays safe and takes advantage of the second round later when playing at home maybe they can advance to the final, it's about strategy and it's worth looking forward to.
The strategy is to win and I'm sure both team coaches will give their best for this semifinal match because this is about not being so stressed when undergoing the second leg. In addition, Bilbao also really wants to be in the Europa League final this season so the team will definitely do everything they can to win early at home, while Manchester United is a team that will not allow its opponents to win early in this first leg because the second leg takes place at Old Trafford.
Well both team will be coming to the pitch to win today but people who plays better and has luck will be victorious in that match. The advantage Atletico Bibao has is this match is that they have good form than Manchester united but so far we have seen that is not longer about form because Manchester united have been wining all these while even with there bad performance and how they are managing to win or scale through is what I don't really know and there pattern is drawing first leg and coming back the second leg to win, let see if it will work for them in this semifinals but if they should qualify for finals then, they will lift the trophy.
