Former Chelsea striker Tony Cascarino would not be surprised if Jose Mourinho manages to convince Cristiano Ronaldo to join him at Stamford Bridge if he returns to the west London club during the summer.

Mourinho is largely expected to leave Real Madrid at the end of the season and numerous reports suggest that he will return to Chelsea who are looking to find a suitable replacement for interim boss Rafa Benitez.

The Real Madrid manager has repeatedly hinted that he will return to the Premier League and there has also been a suggestion that his fellow countrymen Ronaldo will also consider a possible return to England.

Ronaldo has once again been in sensational form for Madrid but there have been rumours suggesting that Paris Saint-Germain and Manchester United were interested in luring the forward away from the Bernebeu.

Having won a league title and the Copa Del Rey during his spell in Spain, Cascarino believes there is a very real possibility that he would consider moving with Mourinho to Chelsea.

"I wouldn't be surprised if Cristiano Ronaldo ends up at Chelsea," the former Chelsea forward told Talksport. "There are lots of times in football where managers leave a club and bring players with them.

"Everyone is assuming that he would go to Manchester United if he was to leave Real Madrid, which he probably will do, because it's their last chance to get a really big fee for him. But Chelsea have broken the [transfer] record so many times and Mourinho has the same agent."

Chelsea owner Roman Abramovich is desperate to keep the club winning major trophies and it is believed that he is willing to once again flex his financial muscles during the summer.

German international Andre Schurrle is largely expected to arrive in a deal that may be in excess of £20million, but should Chelsea decide to try and lure Ronaldo to the club then it would take a huge offer that would most likely eclipse the £50m they spent on Fernando Torres.
