He believes it is important for the future of English football to improve players rather than just buy ready-made stars.
But Puel admits it can be hard for coaches, who don't always get enough time from impatient owners.
Puel said: “English football needs to develop young English players for the national team.
“It will be important to develop all the players, not just to buy the best players in the world.
“It's about technique, intelligence with the ball, and to build something with young players into the team, it's a long process.
“I don't know if all the owners and chairman are ready to respect the results because it's the Premier League."
