Gonzalo Higuain joined his new Chelsea team-mates for training at Cobham as they prepare for the Carabao Cup semi-final second leg with Tottenham.
The Argentina international forward joined the Premier League club on Wednesday on loan until the end of the season.
Higuain was given a lift to training by former Napoli team-mate Jorginho before meeting the rest of the Chelsea squad.
He was put through his paces away from the main group, who are preparing for Thursday night's match at Stamford Bridge against Spurs.
The 31-year-old is ineligible but will be available for Sunday's FA Cup fourth-round fixture with Sheffield Wednesday.
Higuain has reunited with Maurizio Sarri, having worked together at Italy with Napoli.
The former Real Madrid striker's move to Stamford Bridge is expected to pave the way for Alvaro Morata to join Atletico Madrid on loan.
Olivier Giroud is Chelsea's only fit and available forward for the game with Tottenham but Eden Hazard is expected to carry on deputising in the 'false nine' role.
