Southampton fullback Romain Perraud admits his Premier League debut left him gasping for air.
Perraud featured in defeat at Everton last week.
On how the Premier League compared to Ligue 1, the signing from Brest told Sky Sports: "The intensity and number of duels is not the same as in France. In France we have a good championship, but the Premier League is the best in the world.
"After 20 minutes I was breathing heavily, but given I time I think I will be good. The first impression left an impression because of the intensity and fight.
"We scored the first goal and quietened down Goodison Park, but in the second half you could see the power of the fans. We have forgotten the power of fans over the last two years playing without them."
