Moving to England can be a challenging prospect for even the freshest of foreign footballers.
The tempo of a regular Premier League game is generally faster than any other division in the world and the physical demands can take a while for many players to adapt to.
However, experienced Sunderland signing Anthony Reveillere, has suffered no such struggles and has made the transition look easy.
The 35-year-old was brought in by Gus Poyet on a free transfer last month and he has made an immediate impression in the first team, coming in and performing to a high standard straight away.
It is something which has even taken his new manager by surprise and Poyet has admitted his shock at the Frenchman's impressive physical condition today.
"Physically, I’ve been surprised how well he’s done. No doubt," he told the Chronicle.
“Football-wise, not at all. We had seen him in training, and in those first few days he did things with the ball and we said ‘yes, he’s a footballer’.
“That class. That’s why he’s played for the teams he’s played for.”
Reveillere has had a glistening career at the top level, playing for the likes of Valencia, Lyon and Napoli, but he is showing no signs of slowing down.
The 20-time French international made his debut against Crystal Palace, in a 3-1 win, before helping his side claim a point against Everton in their most recent match.
It means that he still has an unbeaten record whilst representing the Wearsiders and he will be hoping to extend this for as long as possible.
Sunderland's form has not been particularly encouraging over the opening part of the campaign, but they are currently clear of the drop zone and they will be aiming to continue to put distance between them and the bottom three after the international break.
The Black Cats take on Leicester City at the weekend in what already looks like it could be a defining match for both clubs' seasons.
