Philippe Coutinho has been unveiled as a Barcelona player after he completed his £145million transfer from Liverpool on Monday.
Around six thousand excited Barcelona supporters turned out at the Nou Camp to welcome the Brazilian to the club after he signed a five-year contract alongside president Josep Maria Bartomeu.
Coutinho did pass his medical but the tests flagged up an injury problem with his right thigh which will delay his Barcelona debut for another three weeks.
The medical occurred in two stages, the first starting at 7.30am local time and the second later in the morning, and revealed the issue with his right thigh.
It means that Coutinho's debut will be delayed and he is likely to miss the upcoming Copa del Rey fixture with Celta Vigo and league matches against Real Sociedad, Real Betis and Alaves.
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.
It didn't stop him taking the field at the Nou Camp, where he performed kick-ups and took part in a 'Rondo' exercise with young players from the Barcelona academy.
On a busy day for the Brazilian, he reported to hospital at 7.30am local time for the first part of his medical, before being taken to the club's training ground for further tests.
He put pen to paper on his contract in the late morning and was then welcomed to Barcelona with a few words from president Bartomeu.
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.
'Everyone knows him as a player, we know about his professional career but what I can say is that it wasn't easy to bring him here. But he wanted to be here and he is part of this new project with Ernesto Valverde and he'll be getting to know us as a club and a team. Coutinho has a lot of family here with him today, which everybody wanted.
'Thank you for accepting the deal. We have spoken a lot over the last few days. You are a player we have wanted to come here for a long time and we thank you for your determination and your motivation to come here. We would also like to thank Liverpool to allow him to come here.'
25-year-old Coutinho smiled when asked to pose with a shirt with his name on the back but no number as that has yet to be confirmed.
He had earlier visited the club megastore at the stadium where he had the chance to print up a replica shirt with his name on the back.
Fans queued around the block to gain access to the Nou Camp and the unveiling ceremony lasted about 15 minutes.
The injury means that Coutinho's debut will be delayed and he is likely to miss the upcoming Copa del Rey fixture with Celta Vigo and league matches against Real Sociedad, Real Betis and Alaves.
It means 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.
