​Stoke City have signed Dery County goalkeeper Lee Grant on a permanent basis, for a fee believed to be in the region of £1.3m. 

Grant signed a six-month loan deal with the Potters on transfer deadline day last summer and with main keeper Jack Butland struggling to shake off a long term injury, the 33-year-old has quickly become a crucial part of Mark Hughes' team. 

Stoke have previously made it clear that they hoped to sign Grant on a permanent basis, but it was initially feared that Derby's asking price for the keeper would be excessively high and the two club's would be unable to reach an agreement. 

However, the Potters have agreed to cough up £1.3m for Grant's services and the Englishman has now signed a two-and-a-half-year deal, which keeps him at the Britannia stadium until the summer of 2019. 


Previous reports from ​Sky Sports have suggested the fee could rise as high as £2m with the inclusion of add-ons, but there can be no doubting that Grant's form this season has been worthy of the price tag and he will now hope to compete with Butland for the right to be the club's long term number one. 

Stoke's Chief Executive, Tony Scholes, has admitted the club are delighted to have agreed a permanenet deal with the player and stated that Grant's form made it easy to seek an agreement with Derby County.

He said (via the club's ​website): "Lee found himself with an opportunity to make an impression in the Premier League and to suggest he has grabbed that chance with both hands would be an understatement. 

"He has shown outstanding form on a consistent basis and we're delighted to have reached an agreement with Derby to make his transfer permanent."

Grant has so far made 15 appearances for the Potters this season and has kept six clean sheets, the most recent of which came in his team's 2-0 win over Watford on Tuesday evening.
