It's Xavi’s last stand on Sunday – his final El Clasico in charge of Barcelona. And things can go one of only two ways.
Win, and he plays out his time in charge in something at least resembling a title race. The gap will be five points with six matches remaining.
Fail to win and there will be no more matches that matter. His legacy as Barcelona coach will be set — more red cards than trophies.
Real Madrid go into Sunday’s game having had a day’s less recovery time after 120 minutes of defending against Manchester City.
