Goalkeeper Kelle Roos is already very familiar with the way new manager Phillip Cocu and his staff like to operate.
The 27-year-old shot-stopper signed a new three-year contract with the Rams in the summer after a string of fine performances in the second half of the 2018/19 campaign.
And he is well accustomed to what Cocu and his coaching team will want and expect from Derby's squad.
Roos played under the manager in the youth set up at PSV during his early years and believes he will be a good fit for the club.
“He wants to play football,” he told RamsTV. “I know him a little bit, so I didn’t expect anything different.
“He is going to ask for a lot of technical ability from us, a lot of possession play and that suits us from what we did last year so it’s good that we are going to build on that.
“It’s clear what the goal is for us and it’s clear we have that in place and we can now kick on and get the preparation we need.”
Roos was speaking from the pre-season training camp in Florida, where the whole squad are being put through their paces in order to get fit for the start of the new campaign.
Speaking after the first day of training, the goalkeeper said: “It was good. It was tough getting used to the environment and heat.
"Breathing is a little bit different but I think we worked hard, got the dust off the lungs and we are ready to go.”
