The Premier League champions have already had a £20m offer rebuffed by the Toffees, but reports have claimed that Jose Mourinho’s side are ready to come in with an improved offer.
Stones himself is believed to be eager to discuss terms with the Londoners, with a potential switch likely to give him a better chance of cementing a spot in Roy Hodgson’s England squad and a the opportunity to play in the Champions League.
Everton are, naturally, desperate to keep the 21-year-old, but Cahill believes that the ex-Barnsley man owes it to himself to make the move:
“In terms of ambition, if you’re a young player in the game, have played in the Premier League like he did a lot last year, and a big club come calling, it’s very difficult to turn down,” he told the Daily Mail.
“You want to achieve the most you can in the short period you have in your career as a professional footballer.
“When a top club comes calling, who you know will be firing on all fronts with competitions and medals, that’s ultimately what you want to be playing for. It’s hard to turn down of course.
“He will look at the club, look at the players, and look at being involved in a squad like ours. When Chelsea came calling for me, it was an opportunity, it was a chance and looking from the outset you may not be sure how it’s going to go.
“But it’s one you can’t turn down, you have to grab it with both hands. Then you have to work as hard as you can to make it work.”
Stones is considered to be one of English football’s finest emerging centre-backs, and his presence at Chelsea would also help the Blues to align themselves with homegrown player quotas.
