Chelsea manager Jose Mourinho has insisted that suffering defeat in their opening pre-season game in the United States is not a "problem".

The Premier League champions took on MLS side New York Red Bulls in a friendly in the Big Apple, and came away with a 4-2 loss.

Despite the result, Mourinho is content with the display as he believes that it was important for his players to be tested.

"They gave us a good training session," Mourinho told the club's official website. "If we came here and won 10-0 I would not be happy because it would mean it was too easy. We needed the game they gave us.

"Obviously we needed to play better than we did in the second half defensively, and there were also too many missed chances, but the intention of pre-season matches is to play, to run, to bring intensity back, so no problem. We are a top team, we have top players. We only started training six days ago.

"They gave us a good match, maybe better than they should, but a very good match. They are not going to forget they beat Chelsea, even if it was pre-season."

Loic Remy and Eden Hazard scored the two Chelsea goals.
