Bilbao, the team that Manchester United will face this season, their level of play is above Manchester United. That's a reality.
Later, I will favor Bilbao because of the quality of their game even though Manchester United this season has performed beyond expectations during the UEFA Europa League with a new format.
This is a fact but I won't write off Manchester United even if Bilbao has a better game level this season than them but still they can do something.
Anyway, it's better not to expect anything much from them and my advice to any Manchester United fan is that they should be grateful they got to this point of the Europa League tournament this season and if they fail to win it or pass this stage, they still did well looking at their over all performance especially in the EPL.
