Kaká has struggled with injury and a lack of form since moving to Real Madrid from AC Milan in the summer of 2009. Recent reports suggest that the player once considered to be among the very best in the world could be on his way back to Brazil in exchange for rising star Neymar. However, there is a chance that he could be reunited with his old manager, Carlo Ancelotti, at Chelsea.

So, here are some reasons why Kaká should be signed by Chelsea.

Why the Premier League?

Chelsea, quite obviously, play in the Premier League, a division that most Brazilians have either stayed away from or not performed well in. Maybe it's the physical style of play, maybe it's the weather. Whatever the reason, Brazilian's, especially attacking players, have not seen all that much success in the Premier League.

Kaká would, therefore be taking something of a risk if he were to come to the Premier League. However, if he was to find success, it would prove that it is possible for Brazilian stars that England is not a waste of time and give players such as Neymar and Ganso more of a reason to come to the Premier League. For Chelsea, a side keen on young Brazilian players, it could be a move that encourages players to follow him, or one that shows Chelsea Brazilian players are not, perhaps, the best option.  

Only Realistic Premier League Destination

Before we get into reasons for Chelsea signing Kaká, other Premier League clubs must be ruled out. 

Manchester City

Kaká has already turned down City once. They couldn't provide him with Champions League football before and it looks like they may still have to fight it out with Tottenham again this year in order to secure a Champions League berth. Even then they will have to make it through qualifying, a major negative.

Tottenham Hotspur

They might have been able to pick up van der Vaart on the cheap, but that's not happening with Kaká, however many injuries he's suffered.

Manchester United

A possibility, but they have not even been linked with the Brazilian, despite his rumoured availability.

Arsenal

Wenger is not the kind of manager to make big money signings, and Kaká would cost.

Outside the Premier League

Brazil looks like a likely destination were Kaká to leave Madrid, possibly in a swap deal for highly rated Neymar. AC Milan might well be interested in bringing back the player they brought to Europe, but they are unlikely to be able to afford the 28 year-old.

Didier Drogba

Didier Drogba is 33; the powerful forward is past his prime and will not be able to lead Chelsea's front line all that much longer. It might, therefore, be a good idea to offload him sooner rather than later. 

Jose Mourinho is a big fan of the Ivorian forward and a move to Real Madrid is not out of the question. Mourinho will be aware that Drogba does not have all that long left, but a part exchange deal would reduce Kaká's price, easing the likely hostility of Abramovich to another big money move so soon after splashing out £70 million or so in a single day during the January transfer window.

Drogba has been valued by the media at around £15 million, with Kaká coming in at anywhere between £25 and £35 million. Either way, Drogba moving to Madrid, or indeed any other club willing to pay £15 million, including a possible return to Marseille, would significantly reduce the amount of cash needed to buy him and also reduce the risk that signing Kaká would represent.  

Fernando Torres

Fernando Torres cost Chelsea £50 million in January and hasn't lived up to expectations yet. While many reckon Torres has lost "it", perhaps what he needs is a change of style. Kaká could be that change. The Brazilian is the type of creative player who could provide the through balls that Torres thrives on, rather than the hit-it-at-Drogba service he has got so far.

Kaká would link nicely between the midfield and attack and provide the type of service Torres has grown accustomed to while playing for the Spanish national team.

Frank Lampard

Frank Lampard is 32 years-old and has suffered from injuries in recent times, much like Kaká. The addition of Kaká would reduce Lampard's workload and keep Kaká's down at the same time. Kaká would, no doubt, have to adapt to the Premier League, and Lampard's presence would allow him to slowly do so. 

Having Kaká and Lampard playing together for a good proportion of matches would provide Chelsea with a great midfield partnership creating and scoring plenty of goals.

He Is Kaká

Kaká's time at Real Madrid has not gone well. He's been injured for long periods of time and hasn't been in great form whilst playing. If he can overcome his knee problems, underneath he is still a man in his prime who has, in the past, shown the world just how good a player he is. He would not be the first player to find a new lease of life after moving from Madrid to London, Rafael van der Vaart did it not so long ago.

"Form is temporary, class is permanent" is a phrase often heard in football, and it applies to the Brazilian. If he can play like he did during his time with AC Milan, Chelsea will have one of the very best players in the world in their side.
