Gary Cahill has joined Jose Mourinho in publicly mentioning John Stones as transfer target of Chelsea FC, urging the player to join the London side from Everton as the club prepare a new A?32m offer as per the Guardian.

According to the Sky Sports News, Chelsea FC had a A?20 million bid for John Stones turned down by Everton earlier in the week, a news also confirmed by the Guardian.

Sky Sports then confirmed later in the week that Chelsea FC were set to table an increased offer for the defender.

The report said:

Sky Sports News HQ understands that Chelsea are likely to make an increased offer for Everton defender John Stones.

Everton insist the player is not for sale, but Chelsea are still hopeful of reaching an agreement to sign the 21-year-old.

The Guardian say that the offer could be in the region of 32 million GBP.

Mourinho, the Chelsea manager, is poised to break the transfer record for a British defender by signing the youngster. A fresh bid a believed to be in the region of A?32m a is expected this week.

Cahill urges Stones to sign

Gary Cahill has seen first-hand from working with Stones on England duty how good the player is and has told Stones the time has come for him to move to Chelsea FC

a Are Chelsea a hard club to turn down? Yes of course. In terms of ambition, if youa 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, ita s very difficult to turn down because you want to achieve the most you can in the short period you have in your career as a professional footballer,” Cahill said

a When a top club comes calling, who you know will be firing on all fronts with competitions and medals, thata s ultimately what you want to be playing for. Ita s hard to turn down of course.”

“He can be a fantastic player”

Cahill has praised Stones, stating that the Everton player has all the attributes to be a success at Chelsea FC

a I saw he was very comfortable on the ball from the first time I saw him with England . ,a said Cahill, who started alongside Stones in wins over Norway and Switzerland in September 2014.

a I am sure in the next few years he will fill out, learn a lot and potentially he can be a fantastic player. The Everton lads speak very highly of him, Phil Jagielka and Leighton Baines in particular, and he is a fantastic lad as well.”

Why are Chelsea FC chasing him?

Stones would be considered as a homegrown player in terms of the Premier League and Champions League and therefore adds to Chelsea FCa s option. Further, the Everton defender would provide cover for Branislav Ivanovic at right-back if required and with John Terry getting older, he could be a long term replacement for the talismanic captain.

The former Barnsley defender is seen in England as the future captain of the national side, having already made four appearances for the Three Lions and his ability was acknowledged by the Chelsea FC captain.

a I have seen a lot of games and I am a big fan of his,a Terry said.a He pulls wide of the box and wants the ball and for a young defender to do that in the Premier League takes some guts.

a He is exceptional with both feet, he is a ball-playing centre half which you need to be these days.

a He is extremely confident. He looks to play from the back and that can only be good for English football that the likes of him are coming through. He is definitely one I have been impressed by.a
