Arsenal are tracking AC Milan striker Carlos Bacca.

Bacca's agent, Sergio Barila, insists the Colombia international is happy in Milan, though a summer departure has not been ruled out.

TMW says the Gunners and Atletico Madrid are watching developments closely.

And a move for Bacca at the end of the season is being discussed inside both clubs' boardrooms.

Indeed, a late January transfer cannot be ruled out as Arsenal and Atletico seek to strengthen their season ambitions.
