Diego Costa has been left out of Chelsea’s squad for the Community Shield clash against Arsenal due to a hamstring problem that Jose Mourinho fears could rule him out of the start of the Premier League season.
The Spain striker was nursing the issue in the build-up to Sunday’s traditional curtain-raiser at Wembley, but was expected to feature.
However, Mourinho opted to rest the 26-year-old as a precautionary measure, and the Chelsea boss is concerned over the striker’s availability for their Premier League opener against Swansea City on Saturday.
“I don’t know if Diego Costa will be available for the start of the season. He had a little problem after the Barcelona game,” Mourinho told BT Sport.
“After that he was training normally and we thought he would be ready, but this morning he was feeling uncomfortable.”
Costa plundered 20 league goals in his first season in English football as Chelsea were crowned champions last May, but was hampered by hamstring complaints, which also affected his final season at Atletico Madrid.
