Chelsea could receive a decision today from Barcelona midfielder Frenkie de Jong over his potential transfer.
Chelsea have agreed terms with Barca for the Holland international, who has been reluctant to leave the Nou Camp.
Sport says De Jong's agents touched down in the city yesterday afternoon and have been in talks with Barca directors since this morning.
Barca want De Jong to accept a move away, but the midfielder is demanding an outstanding €17m he is owed in deferred wages before departing.
Both parties have exchanged legal messages in the past week - despite De Jong still insisting he wants to stay.
