Manchester United made an enquiry over Kaka's availability last month, according to reports.
Spanish publication Sport is claiming Sir Alex Ferguson made contact with Real Madrid over the Brazilian international's availability, but were rebuffed by club president Florentino Perez.
The Red Devils were instantly told the 29-year-old was not available, although the former AC Milan star continues to be linked with a move away from the Santiago Bernabeu.
Clubs from across Europe are thought to be interested in the playmaker, although Manchester United were not one of those previously connected with a move for the player.
Ferguson was linked with a plethora of players in the position during the summer transfer window, but the Old Trafford outfit failed in their efforts to sign any of the targets, including Wesley Sneijder.
Instead, responsibility fell on the young shoulders of Tom Cleverley following midfield legend Paul Scholes' retirement at Manchester United.
The England international initially impressed, but an injury coincided with a slight downturn in fortunes for the club, and left many to predict Ferguson would again look to the transfer window in January after bringing David de Gea, Phil Jones and Ashley Young to the club during pre-season.
Despite his advancing years, Kaka would be a major coup for Manchester United after his recent resurgence in La Liga, although the report goes on to speculate that Perez would only be interested in dealing the player to the Barclays Premier League outfit as part of a mega-deal for Wayne Rooney.
The striker is being linked with a £60 million raid by Jose Mourinho, but Manchester United are unlikely to part with the striker for any fee.
