According to Estadio Deportivo, the Europa League winners have stood firm, just as they have done throughout all the speculation about the future of the Colombian striker.
AC Milan had hoped to reduce the asking price, or perhaps include central defender Adil Rami in a part-exchange deal, given Sevilla have shown an interest in moving for the Frenchman.
However, The Italian giants have been told clearly that Sevilla will only let Bacca leave, if the full €30 million release clause valuation is met in full. The Spanish club refuse to enter into any negotiations. Any bidder must pay that clause in its entirety.
Although it seems the 28-year-old is content with the contractual terms offered, unless AC Milan meet the demands of Sevilla, the door is still ajar for Premier League clubs to make their move.
Although he also explained: "What is clear is that they must meet the release clause, but at this stage nobody has." Which remains the situation with AC Milan.
The other English club mentioned with the possibility of making an approach, is Manchester United. Both they and Liverpool now know that if they're to secure the services of Bacca, they must act swiftly and lodge bids matching the clause value with his club.
From there, it will be up to the player to decide which destination he prefers, although there have been suggestions that a move to either Anfield or Old Trafford, feature highly on the list of Bacca's preferences.
