Bayern Munich refuse to budge on their €50m asking price for Robert Lewndowski.
Marca says the German club is not allowing itself to be pressurised and remains adamant.
It has valued the international attacker at 50 million euros and is not willing to lower that valuation, and this is what has been communicated, once again, to Barcelona after their second offer.
Negotiations are proving tougher than expected at the Camp Nou, as they hoped the player's stance would have some effect.
Despite that firmness, Barcelona remain cautiously optimistic about making the signing a reality.
Various Polish and German media outlets have claimed, in the last few hours, that Barcelona have presented a new, and second, proposal for Lewandowski.
The figures that have come to light are 35 million euros fixed plus 5 million euros in variables.
This offer has been considered insufficient in the offices of Bayern, whose executives are upset and want to keep the pressure on.
