Manchester United are busy preparing for one of their most important matches of the season as they face Athletic Bilbao in the Europa League . United host the Spanish outfit in the second leg of their semi-final and do so with a 3-0 advantage from the reverse fixture at the San Mames Stadium last week. Ruben Amorim's side are just 90 minutes away from booking a place in the Europa League final, where Tottenham Hotspur or Bodo/Glimt would await if victorious over Bilbao. Both United and Bilbao will be without some important players when they meet at Old Trafford this evening. United have Matthijs de Ligt, Joshua Zirkzee, Lisandro Martinez, Diogo Dalot, Ayden Heaven, Toby Collyer and Jonny Evans on the sidelines for the fixture. Bilbao will also have some players unavailable for the game against United. Nico Williams, Inaki Williams and Oihan Sancet are ruled out with injuries, while Dani Vivian is suspended following his red card in the first leg. Here, the Manchester Evening News puts together the full Man United and Athletic Bilbao squads expected to be available for the Europa League semi-final second leg.
