Blues believe offer of a five-year deal will convince forward to make the move south.
Chelsea will make a second improved bid of £30 million for unsettled Manchester United front man Wayne Rooney, according to reports in the Daily Mail.
The west London club have already had one offer of £23.5m, plus add ons worth a further £2.5m, for the England international rejected by the Red Devils.
However, it is understood that new Blues head coach Jose Mourinho is confident of being able to persuade the 27-year-old, who has netted an impressive 197 goals in just 401 matches overall in all competitions for the Premier League champions, of moving to Stamford Bridge this summer.
Chelsea are happy to match Rooney’s current £240,000-per-week salary in the north west, however, perhaps more importantly the Uefa Europa League winners are also prepared to offer the striker a five-year deal to make the move south.
And with his current employers currently even unwilling to start to enter into negotiations over a new contract to remain at Old Trafford, with Rooney’s present deal at United set to run out on June 30 2015, that could be the clincher as far as Chelsea are concerned.
Recently appointed United manager David Moyes though is still insisting that his player, who has been at United since the summer of 2004, is not for sale at any price.
