Barcelona are due to complete the signing of Antoine Griezmann for €120 million (£107m) from Atletico Madrid after a release clause in his contract comes into force on July 1.
Telegraph Sport understands that a contract with the French international was agreed two months ago but is contingent on the release clause - which has led to the delay.
This, however, has been denied by Barcelona president Josep Maria Bartomeu. Only last week he claimed that there was no agreement in place with the forward but sources have suggested it has been finalised.
Griezmann announced in May on social media that he had told Atletico of his intention to leave this summer despite having signed a five-year contract extension last year.
That followed his decision to decline a move to Barcelona at that time when he released another video, called The Decision, which stated that, after much deliberation with friends and family, he had decided to stay at Atletico.
