Chelsea hit by triple injury blow

Arjen Robben career stats

Chelsea are counting the cost of their pre-season trip to the United States after three players picked up injuries.

Winger Arjen Robben did not feature in the Blues' 1-1 draw against AC Milan on Sunday because of a hamstring problem.

Midfielder Claude Makelele (head injury) and defender William Gallas (knee) came off in the second half.

Assistant boss Steve Clarke said of Robben: "We're being over cautious. He said it felt a bit tight and we need to make sure he's fit for the new season."

Robben, 21, made only 18 Premiership appearance for Chelsea last season because of a succession of injuries.

But while the Dutchman is expected to be fit for the start of the new season, Gallas is doubtful.

Manager Jose Mourinho said: "Makelele should not be a problem. It's just a knock on his head.

"But William could be a problem for the first game of the championship."

Chelsea's next match is the Community Shield against Arsenal on Sunday.
