Coutinho has a 400million euro (£355m) release clause in his five-and-a-half year Barcelona contract and is expected to watch his new side’s home La Liga match with Levante on Sunday afternoon.

Liverpool manager Jurgen Klopp said Coutinho was ‘insistent with me, the owners and even his team-mates’ on being allowed to leave for Barcelona.
‘It is with great reluctance that we – as a team and club – prepare to say farewell to a good friend, a wonderful person and a fantastic player in Philippe Coutinho. It is no secret that Philippe has wanted this move to happen since July, when Barcelona first made their interest known,’ Klopp said.
‘Philippe was insistent with me, the owners and even his team-mates this was a move he was desperate to make happen.
‘Despite that, we managed to keep the player here beyond the summer window, hoping that we would be able to persuade him to stay and be part of what we are looking to do.
‘I can tell the Liverpool supporters that we, as a club, have done everything within our means to convince Philippe that remaining part of LFC was as attractive as moving to Spain, but he is 100 per cent certain his future – and that of his family – belongs at Barcelona. It is his dream and I am now convinced there is nothing left at our disposal to change his mind.’
Barcelona confirmed the deal with a video showing Coutinho’s shirt hanging in a locker next to his new team-mates, before later sharing another unveiling clip of them following him on Twitter and Instagram.
