Chelsea defender Cesar Azpilicueta admits he's flagging in the final weeks of the season.

Azpilicueta has admitted that he is struggling, mentally and physically, with the team's workload as they enter the critical stage of the season.

"Physically and mentally it is difficult, because every three days you have a massive game," Azpilicueta said. "We are fighting for every trophy. So you don't have time to think about the last game. You always need to be focused on the next game. It's the first time I have played a lot of games like this, every three days."
