According to Neil Ashton and Chris Wheeler at the Daily Mail, Kaka has been offered to Manchester United on loan. Ashton and Wheeler go on to state that Manchester United manager Sir Alex Ferguson "is giving the 30-year-old serious consideration but has fears about his form and fitness after so many injuries."
If either English Premier League club has any interest in acquiring the midfielder, Real Madrid should make the move, even if it's at a discount.
When Kaka came over from Milan, he was one of the best players in the world. The club signed him for £60 million, a number that was not even too big for the 2007 World Player of the Year.
Unfortunately, injuries have derailed his career to the point where he is now ineffective.
After scoring 31 goals in 61 league games in his last two years in Italy, Kaka has managed to put only 20 in the back of the net in his three years in Spain. He is still an effective passer, but it is safe to say he has not matched his expectations.
Now, he is barely a part of the first team. In the first game of the season against Valencia, Kaka was unable to even get on the field. The teams played to a 1-1 draw, but manager Jose Mourinho did not think highly enough of the 30-year-old to think he would make a difference.
With Luka Modric expected to join Real Madrid soon (via BBC Sports), there will be even less opportunity for Kaka to get on the pitch.
The Brazilian is being paid way too much money—about £250,000 per week—to be riding the bench for Madrid. He can provide other teams with experience and some skill, but he simply has no value on the returning La Liga champs.
Even with the risk of facing him in the Champions League, it will be worth it to sell Kaka while there are potential buyers.
