Filipe Luis' future at Atletico Madrid could move closer to becoming resolved over the next 24 hours.
Atletico are adamant they will not sell the Brazilian for anything less, and his stance is widely reported not to be appreciative of this.
It was reported last week he had even asked the club to drop their demands or buy out the rest of the fee himself , so desperate is he to switch to Chelsea.
Monday is a crucial day for him, as it is the day he is scheduled to return to pre-season training with Atletico.
Spanish newspaper Marca report: "His attitude has left him in a difficult situation and on Monday he will be obliged to turn up at the club and start pre-season training. Watch closely to see what happens next."
The paper report him to be 'in limbo', having told Atletico firmly he wants to leave, and there remains a distinct possibility he could strike in order to try to force a move.
A return to training, should he attend, could see his stance soften. Meeting up again with manager Diego Simeone and the rest of the squad, could persuade him that staying at Atletico is best for his future, rather than joining striker Diego Costa in London.
The Brazilian left-back has not been on international duty this summer, and is expected back among the first wave of returnees.
Chelsea have yet to sign a replacement for Ashley Cole and are claimed to be €9 million short of Atletico's asking price for Luis. In recent days the Blues have been linked with Argentina star Marcos Rojo of Sporting Lisbon as an alternative.
