Chelsea are reportedly waiting for the go-ahead from Roman Abramovich before completing the signing of Bolton defender Gary Cahill.
The Blues had an offer of £7 million accepted for the 26-year-old last week, but Cahill has yet to agree personal terms, and continues to drive a hard bargain.
According to The Mirror, Cahill cannot pen a contract without the approval of Chelsea owner Abramovich, who is expected to say 'yes' to a five-year deal worth £25 million.
Abramovich is currently on holiday, but when he returns it would appear that Cahill's move to Stamford Bridge will be confirmed.
Before his swtich to Chelsea, though, the England international will continue to appear for Bolton, and is likely to feature against Everton on Wednesday night.
The Trotters currently sit bottom of the Barclays Premier League, and even a win will not be enough to lift them out of the relegation zone.
