AC Milan supporters who were relieved to keep hold of star striker Carlos Bacca in the summer may want to temper their expectations after the Colombian international expressed an interest in reuniting with former boss Unai Emery.

Emery, who took the Paris Saint-Germain gig in the summer following three Europa League titles on the trot with Sevilla, managed Bacca for two seasons at the Ramon Sanchez Pizjuan, and if the Rossoneri forward had his way, the two would work together again.

"The reality is that they were in contact with my agent, but they didn't have a vacancy for a non-European player," Bacca told Spanish radio station Cadena Ser, courtesy of ESPN FC.

That international player slot suddenly became available with David Luiz's deadline-day return to Chelsea, again sparking Bacca's interest in working with Emery.

"He is the coach that brought out the best in me and the one that has given me the most confidence," Bacca conceded.

"He is one of the best coaches in the world and I would like to work with him again."

Even with Bacca's quotes, his agent, Sergio Barila, has insisted that his client is happy at the San Siro, telling calciomercato, "Our will is to win with Milan in the coming years so we are open to a renewal, but we will talk about it later."

Under contract with Milan through 2019, Bacca's quotes aren't exactly reassuring ones for supporters of the 18-time Italian champ, especially after a move to West Ham dissolved as the summer transfer window slammed shut on Aug. 31.

"I thought about West Ham a lot, I thought about my family and how they would adapt (to England)," Bacca admits. "The deal did not materialise."

Instead, the Irons dipped into the market for Simone Zaza, Jonathan Calleri, and a loan move for Loic Remy, and while that capital club was desperate for help up top, another one across the English Channel appears more desperate for a forward.

Just ask PSG fans, who watched a straightforward opportunity to kick-off Group A Champions League play with a victory over Arsenal at Parc des Princes fall apart courtesy of Edinson Cavani's repeated gaffes.

Zlatan Ibrahimovic isn't walking through that door, but from the sounds of it, Carlos Bacca might.
