Barcelona have given Neymar permission to leave after Paris St-Germain tabled a lucrative 222m euro (£198m) deal for the forward.
The Brazilian told his team-mates at training on Wednesday that he wanted to leave the Spanish club and was then given permission by Barca manager Ernesto Valverde not to train and to “sort out his future”.
A release clause in his contract set at 222m euros has freed up his options to talk to other teams, which PSG are understood to be ready to pay.

Neymar moved to Barcelona from Brazilian club Santos in 2013 for £48.6 million, and signed a new five-year deal with the 24-time Spanish champions in 2016.
His representative Wagner Ribeiro, who on Wednesday tweeted he was in Paris, said last year that his client had been offered a tax-free £650,000 a week to sign for the French club.
He also said the forward “was close to a move to Manchester United”.
The Brazilian has scored 105 goals for Barcelona, helping them to two league titles, three Copas del Rey and a Champions League crown.
