Berlusconi wants Brazilian back and Allegri to switch tactical set-up to cater for him.
Milan owner Silvio Berlusconi has reportedly told coach Massimiliano Allegri that he wants to bring Kaka back to the club this summer, according to Corriere dello Sport.
Following showdown talks on Sunday which resulted in Allegri being confirmed as Milan boss for next season, it is believed Berlusconi made some demands over players and the style of football the Rossoneri will adopt next season.
The politician is said to have called for a return to a more entertaining brand of football, while also recommending a switch back to the 4-3-1-2 system that served the club so well during the Carlo Ancelotti era.
It is unclear at this stage as to whether Allegri agreed with his recommendations, but Corriere dello Sport, as reported by football-italia.net, have suggested that his requests will begin by looking to re-sign the Brazilian international.
The 31-year-old left the club in 2009 to join Real Madrid in a deal worth €67.2m, but has had problems with both form and fitness in the Spanish capital.
Milan were reportedly interested in bringing him back to San Siro in January, but a move never came to fruition. However, it appears as though Berlusconi is ready to rekindle their interest, and take a more prominent role in first-team dealings.
Kaka scored 95 goals in 270 appearances for the Italian giants, but it remains to be seen as to whether he can come anywhere close to recapturing that kind of form in a second stint.
The Brazilian star has arguably lost some of the devastating pace that made him so feared at Milan, but with Berlusconi pushing for a move he may well be returning to San Siro this summer.
