Marco Borriello would be 'surprised' by any new striker arrivals at Milan, according to the player's agent.
The Italy international is back at the San Siro after impressing with his goalscoring exploits at Genoa last season.
Milan vice-president Adriano Galliani recently admitted that Borriello would have a role to play in Carlo Ancelotti's plans in the coming season.
However, the Rossoneri have been trying to sign Emmanuel Adebayor from Arsenal, and Borriello's agent Tiberio Cavalleri admits the 26-year-old is concerned about his position.
"I am reminded of Galliani's words, who said that Borriello was a fundamental player," Cavalleri told Gazzetta dello Sport.
"It seems clear to me that the arrival of another striker would be surprising because it would mean strategies are changed.
"The aim was to fight for a place with (Filippo) Inzaghi. Borriello always thought it would be useful to come back to Milan to be the third or fourth forward.
"It will be necessary to have good sense, but a solution will be found."
