Chelsea defender Gary Cahill sustained an Achilles injury and will miss the Europa League semi-final clash and boss Maurizio Sarri admits, they are in trouble.

The Blues face Eintracht Frankfurt in the European Cup semi-final on Thursday night.

After Cahill’s injury, Chelsea have just two fit centre backs in Germany.

“Gary Cahill has an Achilles tendon injury,” said Sarri. “We hope to recover him in one week. So we are in trouble with the centre backs. For the last two trainings, we played with Azpilicueta at centre back. We’ve played 58 matches so injuries are typical. We were lucky previously but not in the last 10 days.”

Antonio Rudiger is another player, who is injured and will miss the rest of the season.
