Manchester City's move for John Stones has knock-on effect in transfer market
John Stones became the world's second most expensive defender when Manchester City finally persuaded Everton to part company with him in return for £47.5million.
The fee is a record for a British defender and only Paris St Germain's Brazil international David Luiz has been more costly.
Just hours after arch-rivals Manchester United confirmed the world record £89.5milion capture of France international midfielder Paul Pogba from Juventus, City announced on Tuesday that their pursuit of the 22-year-old England defender had come to a successful conclusion.
Stones, who was included on his new club's squad list for the Champions League qualifiers when it was submitted before the midnight deadline, told City TV: "I just rang my mum and all of family and said, 'I can't believe that I'm here, playing for such a big club, the best manager in the world'. It just all seems so surreal.
"It will take me a few weeks to settle in and get my head around everything, but I'm super excited."
Stones' impending departure prompted the Toffees to step up their interest in Swansea skipper Ashley Williams, and it is understood the two clubs have agreed a fee in the region of £12million.
However, Sunderland defender Lamine Kone will return to training on Wearside on Wednesday amid speculation that Everton have tabled an £18million bid for him.
The 27-year-old Ivory Coast international is understood to have been on Merseyside in recent days after failing to receive an improved contract offer from the Black Cats, but no deal is yet in place.
Meanwhile, Swansea are understood to close to pushing through a club record £15million swoop for Atletico Madrid striker Borja Baston after already landing Sevilla's Fernando Llorente.
The 23-year-old, who scored 18 La Liga goals on loan at Eibar last season, is expected in South Wales to undergo a medical as manager Francesco Guidolin attempts to replace Andre Ayew following his move to West Ham on Monday for a reported £20.5million.
Borja's fee would exceed the £12million Swansea paid Vitesse Arnhem for Wilfried Bony in July 2013 and make him their most expensive acquisition to date.
