Joe Wildsmith did not agree to sign a new contract at Pride Park after a season where he won the League One golden glove for the Rams.
He made a lot of impressive saves and managed to help Derby to a second place finish and promotion to the Championship.
However he didn’t sign a contract extension due to the fact that Paul Warne was making a goalkeeper competition between him and Josh Vickers - Wildsmith wanted job security.
All this means that the Rams will need to add another goalkeeper before the start of the new season that can help them compete in the Championship.
Here are five keepers that Paul Warne could make a move for to replace Wildsmith.
1. Matthew Ryan
Derby have been linked with Ryan who is currently at AZ Alkmaar in Holland. He is due to become a free agent at the end of the month. | Getty Images
2. Marek Rodák
Rodak has also been linked with the Rams. He is the backup at Fulham and will become a free agent very shortly. Rodak is out in Germany with the Slovakia national team as things stand. | Getty Images
3. Christian Walton
Walton is the second choice at Ipswich Town - his contract has been extended by one season so the Tractor boys could likely want to sell him this summer so as to earn a fee for the 28 year-old. | Getty Images
4. Remi Matthews
Matthews is another Premier League backup who could command a place in the first team of a Championship club. He would be more of a short term option as he is over 30. | Getty Images
