PSG have not won at the Stade de la Mosson in three visits, losing twice and conceding three goals in each reverse. After setting a European record with 14 successive league wins from the start of last season, Thomas Tuchel's men have already suffered three reverses this term at the hands of Stade Rennais FC, Stade de Reims and Dijon FCO.

As they seek to reinforce their five-point advantage at the top of the table against a Montpellier side handily placed in sixth and looking to move into the top three, Bernat urged the champions to be on the guard.

"Last year we didn't lose any of our opening 14 matches," the Spain international told This is Paris on BeIN SPORTS. "This year, after winning 4-0 in the Classique, we were in a great position, but we know that in football you always have to go out and be 100 percent focused on the field. Any team out there can beat us, so we need to learn from our mistakes and make sure we win the next match."

Bernat moved to Paris from Bayern Munich in summer 2018 giving him a headstart in settling into life in France compared to more recent Spanish-speaking arrivals Keylor Navas, Sergio Rico, Pablo Sarabia and Ander Herrera.

He has used that knowledge to help them find their feet quickly and become part of a dressing room that is as happy as it is talented.

"Pablo is a year older than me. I think we played together once for Spain under-21s, but I knew him before that because when he was young he was often talked about as one of the biggest talents in the Real Madrid academy. I get on really well with him, we are close and I am really pleased that he is here," explained the versatile ex-Valencia defender.

"When new players come in, it is important to approach them and help them integrate. I have tried to do that with them. We have a lot of Spanish speakers in the squad, with all the South Americans, and they have settled really quickly. The truth is that we have a fantastic dressing room.

"We go out together sometimes, especially Pablo and I, but also Sergio and Ander and the South Americans too, along with Marco Verratti and Kylian. We have a great group of players and we enjoy doing things together off the pitch."
