Having played in the Top 14 with Toulon, Chris Ashton believes the pace of play in the league is harming France at international level.
Chris Ashton believes the slower speed of the Top 14 is having a detrimental effect on France's international hopes, but the England wing knows he and his team-mates will face an "angry" and "desperate" team at Twickenham on Sunday.
After pulling off a tremendous win over Ireland, last year's Six Nations champions and Grand Slam winners, England will be heavy favourites to beat a French team that began their campaign with a dismal defeat to Wales.
France led 16-0 in Paris, but then gifted Wales two tries and were beaten 24-19.
England wing Ashton, who enjoyed a stint in France at Toulon, told the media: "The speed of their domestic game is definitely affecting the step-up to international level.
"The Top 14 is a slow, stop-start game. When you're in an international game it’s the highest intensity it could possibly be whereas their league isn't at that level. I'm speaking from experience. It's not anywhere near."
"Maybe that step-up shocks them in that first couple of games but they will get up to speed very quickly.
"I'd definitely say the Premiership is a lot more intense. The ball is in play a lot more and the whole game is a lot quicker."
Looking ahead to France's visit to Twickenham, Ashton added: "It will be an angry French team, desperate to make up for the last 20 minutes of that game against Wales.
"They will be up for the game against us more now than they would have been had they got the win. A lot of the French game is based on emotion but they’ve got a lot of good players in there too.
"If we know anything about the French, it is that they love a reaction. Their backs are against the wall and we expect nothing less from them really than putting everything into the situation. They’ve got to get a win and make up for last week."
