Chelsea captain Cesar Azpilicueta admits he's concerned about this season's workload.

Azpilicueta has branded the current schedule for footballers as "crazy" as games are crammed in before the World Cup gets underway.

"It's difficult and it's sad because as players you want to go to the World Cup, but we have this schedule where we have to play for our club and do our best," said Azpilicueta via football.london.

The 33-year-old also added how player welfare is becoming increasingly important during this period: "We are fighting a lot for player welfare because the schedule is crazy.

"Sometimes we have to consider everything and I think we are in conversations with FIFA. It's difficult because I understand that the fans want to see football.

"We have five subs now but we have in our team a couple of injuries that make it more difficult to rotate."
