Philippe Coutinho trained for the first time with his Barcelona team-mates on Saturday.
Following his £145million move, Coutinho had been training alone to continue his recovery from a thigh injury after being ruled out for three weeks.
But he joined up with his team-mates for a session on Saturday as they prepared for their league match against Real Betis on Sunday.
Coutinho was pictured next to fellow Brazilian Paulinho as well as other new signing Yerry Mina.
Coutinho could make his debut in the Catalan derby against Espanyol – the club he played at on loan from Espanyol in 2012 – on February 4.
The Brazilian midfielder described his move – the second most expensive in football history – as a ‘dream come true’ as he was officially unveiled at the Nou Camp.
Speaking at the official unveiling of Coutinho, club president Josep Maria Bartomeu said: ‘All Barcelona fans around the world are pleased to meet the new Barcelona player Philippe Coutinho.
‘We wanted him last summer, we have been working for weeks and months on this deal but one of the most important aspects was that he wanted to come he.
‘He was patient and that was a determining factor in bringing him here. I am delighted to announce the signing of one of the stars of world football.’
Barcelona are currently eight points clear at the top of La Liga and will be looking to extend that lead against ninth-placed Betis.
