There's a mixture of Premier League and FA Cup games in England this weekend.
Manchester United face a crucial game at West Bromwich Albion in the Premier League. David Moyes and his team will look to bounce back from a demoralising defeat to Olympiacos in the Champions League last week.
There's a scrap between two relegation-threatened teams in South Wales, where Fulham visit Cardiff City. Meanwhile, Chelsea can stretch their lead at the top of the table with a win over Tottenham Hotspur at Stamford Bridge.
In the FA Cup, Everton travel to Arsenal on Saturday, while holders Wigan Athletic visit favourites Manchester City on Sunday.
In La Liga, Spain's three title chasers are all in action this weekend.
Barcelona travel to Real Valladolid in Saturday's early game, while third-placed Atletico Madrid visit Celta Vigo in the evening.
If Barcelona win, Real Madrid will have the chance to return to the top of La Liga on Sunday against Levante at the Bernabeu.
Meanwhile, Juventus can further extend their lead at the top of Serie A when they play fourth-placed Fiorentina in Italy's early game on Sunday.
Perhaps the bigger game is in Naples, though, where third-placed Napoli host second-placed Roma.
Elsewhere, Milan visit Udinese on Saturday while neighbours Inter host Torino on Sunday.
