The Portuguese's side are level 1-1 on aggregate heading into the away leg of their tie against Manchester United but will again face the Premier League leaders without captain Iker Casillas, who remains sidelined with a hand injury.
The English side, meanwhile, will be without utility player Phil Jones, who limped out of their FA Cup clash against Reading with an ankle injury, but can call on Rio Ferdinand in defence after recovering from the flu.
