Boubacar Kamara has suffered a second serious knee injury of his Aston Villa career

An injury crisis and a returning hero. Aston Villa's season continues to take sharp turns.

Douglas Luiz's arrival from Juventus solves one problem after Boubacar Kamara was ruled out for the season and John McGinn and Youri Tielemans were also sidelined.

Their absences come at a crucial stage of the season with Villa third in the Premier League, into the FA Cup fourth round and with the chance to top the Europa League group phase on Thursday night, when they host Red Bull Salzburg.

If Villa reach the finals of the Europa League and FA Cup they will play 61 games this season - so has Unai Emery got a squad deep enough to succeed and win Villa's first major trophy since 1996?
