Chelsea defender David Luiz has said that the club cannot allow themselves to focus on more than one game at a time.

The Blues beat Championship outfit Birmingham City on Tuesday in Roberto Di Matteo's first game in charge, but the Brazil international insists that his focus instantly turned fully to this afternoon's game against Stoke City.

"It's nice we won the game [against Birmingham]," he said. "Now it's a new start.

"Tomorrow is the most important game, and then after that we will start thinking about the next one.

"It's not important to think about the future until after the Stoke game. We need to press from the first minute until the last if we want to win."

Chelsea could move back into the top four with a win this weekend.
