The Nerazzurri are still on the lookout for a new centre forward and they have turned their attention to the Colombia international.
And while Sevilla are holding out for €20 million, it is believed they would agree to lower the asking price to €15 million in case at least a third of the amount is paid in the first instalment.
Another good news for Inter is that los Rojiblancos are keen on Zdravko Kuzmanovic, a player who the Nerazzurri plan to offload this summer.
Carlos Bacca joined Sevilla from Club Brugge last summer and he proved an instant hit at Ramon Sanchez Pizjuan, notching 21 goals in 52 competitive appearances.
An injury prevented him from making more than three appearances for Colombia at the 2014 World Cup, but his second-half cameo against Brazil hinted what he is capable of.
