Chelsea will launch a second bid for Everton defender John Stones in the next 48 hours, according to the Mirror.
The Blues have already had one offer for the 21-year-old turned down worth around £20 million, but will not be deterred by Everton's reluctance to sell and will lodge an improve bid of £26 within days.
Everton are believed to be holding out for a fee in excess of £30 million before they sell up, and the saga is threatening to turn nasty, with the Toffees accusing their Premier League rivals of trying to unsettle Stones.
The talented youngster enjoyed a breakthrough campaign in the Premier League last season and earned a call up to the senior England team - and now he could be about to make a big-money move to the champions.
Stones is said to be keen on a move to Chelsea, while Manchester United were linked with a swoop for his services over the weekend.
Everton boss Roberto Martinez has hit out at Chelsea over their attempts to sign Stones, who featured for the club in their 3-1 win over Hearts on Sunday. However Mourinho insisted in a recent interview that Everton have not closed the door to selling up, and the Mirror say they will accept an offer of £34 million.
Stones is viewed as the natural heir to John Terry at Chelsea, with the veteran skipper edging towards the end of his playing career.
Chelsea want him before the Community Shield showdown against Arsenal on Sunday, however the saga is set to run for some time. The fact that the Blues will offer £26 million - still £8 million short of Everton's valuation, which would make him the most expensive defender in Premier League history - will ensure that is the case.
This whole transfer saga has an air of inevitability about it - generally speaking if Chelsea want a player they will get him.
If and when the Blues do get their man they have their future centre-back pairing in place with Kurt Zouma at the club. Gary Cahill was far from convincing last season and while Terry was superb he can't go on forever, and this season could even be his last.
The only potential spanner in the works is interest from Manchester United, who can offer Jonny Evans in return, however Chelsea are clearly in the driving seat as things stand.
