Silvio Berlusconi  says AC Milan  will be looking to sign players in their early 20s with world-class potential, rather than older, established names.The San Siro side said farewell to Alessandro Nesta, Gennaro Gattuso, Clarence Seedorf, Zlatan Ibrahimovic  and Thiago Silva ahead of the 2012-13 campaign, and Berlusconi is determined to bring in young talent as replacements for the aforementioned stars."We are looking for players who can become true champions in the future, players in the age category of 22 to 23," Berlusconi was quoted as saying by La Gazzetta dello Sport."We will mainly sign young players to rebuild the team. [Marco] van Basten has recommended us a young Dutch player and he agrees with our decision to count on youngsters."The Milan boss then went on to discuss Stephan El Shaarawy, and stressed that the Italy international cannot be compared to any other current player."El Shaarawy does not remind me of any other player as he's unique and a very special player. He's one of the discoveries of the season and has been a revelation," he added."El Shaarawy wants [Mario] Balotelli to join because they're friends? They could play cards together if they're friends."Berlusconi also had his say on the possible arrival of Pep Guardiola as the club's head coach, and insisted that the Rossoneri have faith in Massimiliano Allegri."We have an excellent relationship with Allegri and will continue with him," he continued."Of course, every team would like to have a coach like Guardiola. There are three teams that have left their mark on football. Johan Cruyff's Ajax, the 'Dutch' AC Milan and Guardiola's Barcelona."
