KELLE Roos will press his claim to be Derby County’s number two goalkeeper behind Lee Grant next season.
Adam Legzdins spent this season as back up to Grant, who was ever-presnt.
Legzdins’ contract has not been renewed and he has left the club, leaving Roos next in line.
Derby felt they were in a position to release Legzdins because of the progress Roos has made since the 21-year-old Dutchman joined the club from Nuneaton Town in January for an undisclosed fee, believed to be around £30,000 plus add-ons.
The Rams will play a pre-season friendly at Nuneaton in July as part of the deal.
Simpson says Roos has impressed.
“Kelle has been outstanding since he has come in,” said Simpson. “He is developing really well and looks like he could be a good keeper.
“We’ll monitor him over pre-season and see if he’s up to being number two, and that’s goalkeeper coach Eric Steele’s department.
“We felt because of Kelle we were in a position to release Adam Legzdins.
“Adam is also at a stage in his career when it is about playing football.
“He has been superb and has pushed Granty all the way in training.
“That is why Lee Grant has done so well because he knows Adam has been breathing down his neck.”
The Rams are set to add to their goalkeeping department by signing former Newcastle United reserve keeper Jonathan Mitchell on a one-year deal.
The 19-year-old was recently released by Newcastle.
Hartlepool-born Mitchell did not make a senior appearance for the Magpies but gained first-team experience during a loan spell with non-League Workington.
