Chelsea boss Rafa Benitez knows his players are facing a decisive week.

There are numerous hurdles to negotiate, beginning this week at Steaua Bucharest, who knocked Ajax out of the Europa League, and then next Sunday's FA Cup quarter-final at Manchester United.

"One game at a time," said Benitez, following Chelsea's 1-0 Premier League defeat of West Brom. "We have to go to Bucharest before we can concentrate on this (the United) game.

"Both games are important, but one is just one game and one is two legs."
