Chelsea will have to smash the British transfer record again if they are to land prime target Edinson Cavani. Blues will need to go to £53million after French moneybags Paris Saint-Germain began an all-out assault to persuade Cavani to leave Napoli for Ligue 1. And with the French champions prepared to meet Napoli owner Aurelio De Laurentiis' demands for the full buy-out clause written into the Uruguay striker's contract, it leaves Chelsea facing a significant dilemma. While Jose Mourinho wants the Uruguayan, believing he is the ideal line-leader for next season's revamped team, Chelsea have signaled they will not be held to ransom. The Stamford Bridge outfit were burned by the record £50m fee they were forced to pay Liverpool for Fernando Torres in 2011 and do not want history to repeat itself, especially with the Spaniard now set for a cut-price exit. Although Chelsea are willing to meet Cavani's demands for a five-year contract worth around £7.5m - £150,000 per week they have so far refused to go above £45m. The Blues' strategy was a belief that, despite Napoli's insistence that the full contract clause is met, the Italian side would eventually come to the table, especially if Torres could be included as a make-weight in the deal.
