Kevin-Prince Boateng says he is physically well after completing his shock move to Spanish powerhouse Barcelona on Tuesday.
The 31-year-old, who joins from Sassuolo, has signed a six-month deal which expires in the summer.
The Ghana international, who has enjoyed an Europe-hopping career, is the latest addition to the Catalan squad.
However, there are long-held fitness concerns about the former AC Milan star but he says he is fully fit to kick-start his career with the European giants.
"I'm doing very well physically, I played 90 minutes for Sassuolo on Saturday." he said
Barcelona's decision to sign the attacking midfielder has shocked the world as it was not anticipated in a remotely manner.
But the agent of the Ghana star has pulled a massive transfer coup by agreeing a deal with the Spanish giants.
Although born in Germany, he made 15 appearances for Ghana while his half-brother - Bayern Munich defender Jerome Boateng - plays for Germany.
Barca were short of attacking options after the La Liga leaders sold Paco Alcacer and Munir El Haddadi this month.
