It’s a huge La Liga clash as Athletic Bilbao host league leaders Barcelona at San Mames knowing that avoiding defeat would be a huge coup for the club.
Barca suffered then first loss under the guidance of Gerardo Martino mid-week when Ajax triumphed over the Spanish champions 2-1 in the Champions League.
That being said the manager has got the team playing superb football in the top tier in Spain and the Catalans are top of the pile.
However, both Atletico Madrid and Real Madrid are hot on their tails and three points against Athletic Club is a must if they want to maintain their lead.
Martino has a selection headache as several high profile stars are out of the clash, with Lionel Messi, Victor Valdes, Carles Puyol and Dani Alves all sidelined.
It means that youngsters Adama Traore and Patric are both included in the squad and could well feature in the tie.
Bilbao go into the tie sitting in fifth place but their lack of goals is beginning to become worrying as none of their strikers have found any form as yet.
