Chelsea boss Jose Mourinho admits they'll be short of numbers for the Premier League opener against Burnley.
Mourinho has admitted Oscar, Willian, Ramires and Andre Schurrle - who all returned late from the World Cup after Brazil made the semi-finals and Germany triumphed - will not be fully ready for the club's trip to Burnley on August 18.
But Eden Hazard made his first appearance in a Chelsea shirt this summer after coming on as a second half substitute in the 3-0 defeat to Werder Bremen on Sunday.
"Eden trained two days, Didier trained three days. They need these matches to look for their form," said Mourinho.
"It worries me because the boys (returning late from the World Cup) that start tomorrow don't have time to get ready for the start of Premier League.
"We cannot deny that our first half was poor. The reaction was good in the second half. Eden brought something to the game."
