The first picture of Diego Costa training as a Chelsea player has been posted online by the club's official Twitter account.
Costa flew out to Austria today as part of a 26-man squad which will be based in the country for the next fortnight for a training camp, with several friendlies arranged against European sides.
The £32 million striker sealed his switch from Atletico Madrid earlier this month, but had been on leave after his participation at the World Cup with Spain.
International teammate Cesc Fabregas and his former clubmate Filipe Luis are also among those who have travelled with the squad.
Costa scored the goals last season which led Atletico to winning the La Liga title, and was exactly what Chelsea were lacking as they fell short in the Premier League.
It is for this reason his signing was so eagerly anticipated, and if he can stay fit and avoid the injury troubles which plagued him at the end of 2013/14, he could be the game-changer Chelsea have been yearning for.
