Barcelona take on Athletic Bilbao at the Camp Nou in the Copa del Rey quarter-final second leg clash.
The reigning Spanish Cup title holders beat Bilbao 2-1 away from home in the first-leg but face a number of injury doubts.
Andres Iniesta, Sergio Busquets and Arda Turan all came down with the flu earlier in the week and Luis Enrique revealed that he will make a game time decision over whether they will play or not.
“Arda, Iniesta and Busquets have the flu,” Enrique told his prematch news conference.
“We will see how they feel tomorrow.”
Turan has featured in every Barcelona game since making his debut against rivals Espanyol in the Spanish Cup Last 16 earlier this month and will be expected to make an appearance if fit.
Barcelona will however, definitely be without Luis Suarez and Jordi Alba while Lionel Messi is also a doubt.
Arda Turan says in Barca dressing room, "nobody makes jokes at me because they're afraid I'll throw shoes at them." https://t.co/lnV7M8raQp
