AC Milan star Ronaldinho and Inter Milan ace Javier Zanetti have welcomed a return to the San Siro for Kaka.
Kaka's future at Real has been the subject of speculation again in recent weeks after a disappointing debut season at El Santiago Bernabeu last season.
Kaka's father and agent was spotted at Milan's headquarters on Thursday but the Rossoneri were quick to play down the rumours of a return to club by stating his father was there for "bureaucratic reasons".
Kaka's fellow Brazilian Ronaldinho admits he would be delighted to see the playmaker make a return to Milan.
"If he did return to Milan I would welcome him. He is a great champion and made history with this club," said Ronaldinho.
At rivals Inter ace Zanetti would also like to see Kaka join the Nerazzurri.
"Kaka is a great champion and, if he comes, he will reinforce an already strong group," said Zanetti.
"We would be happy to have him. He would be received with open arms just like any other champion."
Earlier this week, Inter Milan president Massimo Moratti denied reports the club have made a move to sign the Brazil international.
