Marveaux insists life in the French league is a stroll in the park compared to the demands of the English top flight.
The ex-Rennes winger regularly covers seven miles during games.
And he admitted: "I don't know exactly how much more I'm running in this country, but it feels like I am.
"In the Premier League it seems like you're running all the time, every minute. There's no time to rest during a game.
"That's the big difference between here and France. There, you have a lot more time on the ball.
"It takes time for your body to get used to the pace and energy of the game here and I now understand what's required to play regularly in the Premier League.
"I think the manager can see the big improvement in my game in terms of workrate."
