Milan Vice-President Adriano Galliani has warned Antonio Cassano that he will have to fight for his place in the side.
Competition for an attacking jersey is fierce at San Siro with Zlatan Ibrahimovic, Alexandre Pato, Robinho, Antonio Cassano, Pippo Inzaghi and Alberto Paloschi at the club.
"Years ago we had practically agreed a deal for Jurgen Klinsmann," Galliani told reporters on Wednesday.
"It was almost done, but it never happened because his agent asked that the player be guaranteed a first team shirt.
"Nobody is assured of a place in our side, but Antonio can certainly be of use to us," the official underlined.
Galliani was also inevitably asked about Napoli chief Aurelio De Laurentiis' statement that Marek Hamsik was a better player than Pato.
"Hamsik is a Napoli player so it is normal that De Laurentiis thinks that way. It's not a problem because Pato is ours and Hamsik belongs to Napoli.
"Hamsik is not part of our plans and we've never been interested in him. We'll keep Pato."
The San Siro chief also insisted that Stephan El Shaarawy would spend next season with them after his move from Genoa, but denied links with Didier Drogba and Juraj Kucka.
"El Shaarawy will stay at Milan," he said of the 18-year-old attacking midfielder.
"I'm convinced that he is mature enough for Serie A. We'll soon see what his value is, but I am sure that he can become a champion.
"Drogba is a suggestive name, but we are ok in attack right now. As for Kucka, he is a Genoa player and the possibility of him wearing our shirt can be excluded."
