The La Liga club sold Bacca to the Rossonerri two years ago, but the Columbia international has failed to make his mark in Italy and has reportedly fallen out with coach Vincenzo Montella.
Following admissions by the Milan club that they are in the market for a new striker, the 31-year old’s agent acknowledged that his client is actively seeking a transfer and would ideally like to rejoin his former club.
“It is now well known that Carlos wants to return to Sevilla,” Sergio Barila told AS.
“He had a splendid personal and sporting experience in that city, which is why he wants to return.
“This is an important year for players, that of the World Cup, so he needs to play in order to take part. He is in good shape physically and ready for a great season.
“When Bacca arrived at Milan, he signed a five-year contract and had every intention of seeing it through to the last day of that agreement.
“Unfortunately, there was a change at the helm and now the Rossoneri have other ideas.
“The best thing to do would be to find a solution that makes everyone happy.”
