With Real Madrid's superstar forward Cristiano Ronaldo showing public unhappiness with his current club, it is thought that Chelsea's mega rich owner Roman Abramovich is closely watching the situation and is ready to wade in with an offer in January, when the transfer window re-opens for English clubs.

Ronaldo has a €100m buyout clause in his contract and it is unconfirmed as to whether Abramovich will be willing to match that. But he is hungry to become one the most dominant club teams in the world, and Cristiano Ronaldo is certainly one of the best current players in the world.

The former Manchester united hero has become unhappy at Madrid following issues with backroom staff. In his latest game for Madrid, he failed to celebrate after scoring a goal and has since made a statement confirming that he is 'sad'.

In the same statement he has also confirmed that he remains dedicated to Real Madrid, but did not clear up his long term future. One feels that he would be interested in a move back to the Premier League.

His current manager Jose Mourinho is also keen on a similar move back to England and with his history with Chelsea, he has some unfinished business there that he would love to take care of with the help of the Portuguese international captain.

Chelsea are looking to bring in some of the hottest prospects in the world within the next season or so and it now seems that Ronaldo is on the shortlist, up there with the likes of Neymar and Radamel Falcao. 

Ronaldo has never been shy of controversy even during his time in the Premier League, but he has grown in stature during his recent years and adapted to become one of the greatest players the sport has ever witnessed.
