Mount, currently with Derby, spent last season on loan with Vitesse and believes the experience of playing overseas can help young footballers.
"I would say to all young players game time and experience is the most important thing," Mount told talkSPORT.
"For me to go out on loan and play in a top professional league and gain experience, rather than sitting in the Chelsea Under-23s.
"I didn't want to do that, I'd already had a year playing Under-23s and I felt that I needed to move on and test myself away from England.
"It was the best decision I made because I went out there, gained so much experience and playing time, and that set me up moving on."
