Javier Mascherano is passed fit to start Barcelona's Champions League clash with Olympiakos this evening.

Mascherano dropped out at the last minute of Barca's 2-0 win at Athletic Bilbao over the weekend and was a doubt to face Olympiakos, but he replaces Gerard Pique, who is suspended for the match.

Elsewhere for the Catalans, Nelson Semedo comes in at right-back, allowing Sergi Roberto to move into midfield, and Paulinho keeps his place after scoring at San Mames.

The Blaugrana will qualify for the Champions League knockout stages if they better Sporting CP's result against Juventus.
