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.
Costa, 33, said: “I was scared to death. Holding that chain I kept thinking, ‘What if this wolf thinks about jumping on top of me?’ and then the three of them did.
“I was a little scared then. Those were wolves, not dogs. It was a cool experience but not a very comfortable one. I have five dogs, but they’re not wolves!”
Now his full focus is on scoring goals for Wolves and providing trophy-winning experience into a young, talented squad.
