Possible lineups for Olympiacos v Aston Villa

Aston Villa face probably their biggest game of the season so far when they visit Greek side Olympiacos in the second leg of their Europa League semi-final tie at the Karaiskakis Stadium. Kick-off at 21:00 CEST.
The Villans, against all odds, suffered a painful and unexpected defeat at Villa Park against Jose Luis Mendilibar's side, thanks in large part to a hat trick from striker El Kaabi. The Premier League side will therefore have to turn the tie around in a territory that is hostile to most teams despite a two-goal deficit.
Unai Emery, who has been in charge of Villa's fortunes since his arrival, will try to mastermind a plan to storm the Greek side's home ground and leave his team just one step away from a third European title in their history, 40 years after their last when they lifted the UEFA Super Cup in 1983.
Olympiacos possible starting XI: Tzolakis (GK); Rodinei, Ndoj, Restos, Ortega; Iborra, Hezze; Masouras, Chiquinho, Podence and El Kaabi.
Aston Villa possible starting XI: Martinez (GK); Konsa, Carlos, Torres, Digne; Cash, Luiz, McGinn, Bailey; Diaby and Watkins.
