Manchester United winger Nani says they cannot think about their games against Chelsea too soon.
The business end of the season sees United and third-placed Chelsea, nine points behind with a game in hand, clash in the first leg of their Champions League quarter-final on Wednesday.
But Nani vowed: "No one in the dressing room is thinking about Chelsea yet - only West Ham.
"The real truth is every match between now and the end of the season is like a cup final. We can't give our rivals anything."
