In fact, the 30-year-old Kaka may not be going anywhere, according to Real Madrid manager Jose Mourinho.
The reason? There hasn't even been an offer made for the 2007 FIFA World Player of the Year.
Mourinho hinted that Kaka could still leave the Bernabeu but that nobody had shown an official interest in taking the Brazilian playmaker, whose salary demands are reported to be significant.
"Kaka's situation is completely different," Mourinho said. "We have no official request for Kaka; we do for Nuri."
While it makes sense that most teams would balk at paying an exorbitant fee and meet the oft-injured Kaka's salary demands, Manchester United's van Persie's transfer seemingly signaled an all-in 2012-13 campaign for Sir Alex Ferguson and his Red Devils.
And with finances never being a concern for a cash cow like Man U, it makes little sense that Ferguson is yet to make an offer for the Brazilian midfielder.
Even at 30, Kaka is a perfect fit for Man U's needs and could even come over via a one-year loan agreement, according to Daily Mail. A short-term agreement makes acquiring Kaka the type of low-risk, high-reward move that could bring the Glazer family their fifth title since buying the club in 2005.
Should Manchester United make a bid for Kaka?
And let's not forget about the fact that Manchester City's 2011-12 Premier League championship completely flipped the script on how to build a team.
Like it or not, Man City's strategy of spending exorbitantly on the world's top talents created a Frankensteinian team that looked unstoppable for much of last season. They also open the 2012-13 campaign as 5/1 favorites (according to Bovada.lv) to come away with a second straight championship after previously going 44 years without one.
Ferguson's recent strategy of bringing young talent to Old Trafford will undoubtedly build a long-term legacy long after the manager has retired, but it won't atone for another second-place finish.
While Roberto Mancini's club will never make a dent in the popularity of the world's most beloved sports franchise, taking home the Premiership crown is all that matters.
Even with their advancing age and injury-prone status, bringing in players like van Persie and Kaka could help Manchester United win now without sacrificing the future.
Ferguson needs to realize that and make a quick call to Mourinho before it's too late.
