Chelsea are all set to sign Barça striker Aubameyang and should make a final offer soon

Pierre-Emerick Aubameyang's future remains undecided, despite having an agreement with Chelsea for the next three seasons, as the negotiations between the two clubs remain deadlocked.

Until now, the English club have made a formal offer of 15 million euros plus Marcos Alonso, which Barça rejected.

The Spanish club does not want to include the wing-back in the operation because of registration problems and are prioritising cash.

FC Barcelona want 20 million plus variables, but it seems that Chelsea are not in favour.

The transfer of Aubameyang was expedited earlier this week and was heading in the right direction, but the disagreement between the two clubs has been a roadblock.

Barça want to wait before acquiring Marcos Alonso till they are assured of their finances, to avoid further registration problems. Signing him now will be a gamble even for five million euros, which is a real steal for an international.

Chelsea have so far failed to understand, and negotiations have been stalled. But Thomas Tuchel's keen interest in having the striker on board kindles hope for the deal.

The two clubs will likely agree to an intermediate figure, though Barça are being very firm in defending their interests. The delay in the transfer is making it difficult to register Koundé, but the club are convinced that they have him available this weekend against Valladolid
