Wolves have signed former Chelsea striker Diego Costa on a free transfer until the end of the season.

The 33-year-old has been without a club since leaving Brazilian side Atletico Mineiro in January.

Costa completed his medical on Thursday last week as cover for new signing Sasa Kalajdzic, who suffered a cruciate injury on his debut.

"Diego will bring something unique to our dressing room and on the pitch," said Wolves chairman Jeff Shi.

"We are absolutely delighted to welcome Diego Costa to Wolves, and back to the Premier League.

“A serial winner with a wealth of experience at the highest level, Diego will bring something unique to our dressing room and on the pitch, and we look forward to his impact at Molineux and Compton this season."
