Laurent Blanc has dismissed suggestions the race for the Ligue 1 title is a two-team contest between his Paris St Germain and Claudio Ranieri's Monaco.
Lille have broken up the expected duopoly at the top of the table, beating Monaco last weekend to jump above the team from the tax haven.
Monaco's spending since Russian Dmitry Rybolovlev bought a controlling stake two years ago has rivalled PSG's own outlay, with a widely-held theory being that the two should be jostling alone at the top of the table before long.
Nice can only dream of the resources available to their neighbours from along the Cote d'Azur, and ahead of Saturday's tussle in the capital they stand 11th in the league, albeit only one point behind fifth-placed Marseille.
Were it not for Lille's fine early-season form, PSG and Monaco would be sitting handsomely atop the standings, given that after 12 rounds of games fourth-placed Nantes are already eight points behind the Parisian leaders and five adrift of the principality outfit.
Lille have given everyone food for thought though, not least PSG head coach Blanc.
``They are showing they deserve to be there,'' the former France manager said in his press conference. ``Even if you were saying that the league would only be contested between Paris and Monaco.
``In my opinion, five clubs are in the fight for the three top places.''
Blanc is savouring his first season in charge at the Parc des Princes, but said: ``There is pressure everywhere because you always want to achieve your objectives.
``A season lasts a long time, you must know how to manage things because everything can race by very quickly.
``It's enjoyable to be at the head of such a club, a luxury to coach such players because they showcase our work.''
Blanc admires Claude Puel, manager of Nice. Puel spent his entire senior playing career with Monaco and later managed the team to the Ligue 1 title, before going on to boss Lille and Lyon.
``He's a competitor so I think he'll come to Paris and won't compromise on his style of play,'' Blanc said.
``I hope that they will show their ambitions on the pitch, because that's often synonymous with an open game.''
Blanc said, according to his club's official website, that striker Edinson Cavani should be fit to face Nice after training well since sitting out the Champions League draw against Anderlecht with a leg injury.
Puel has braced his visiting team for a tough fixture, saying: ``(PSG are) a very beautiful team, it's only a bonus for us to be able to play them. It allows us to raise our game and concentration against a very high-level opponent.
``Every footballer would love to play this type of match against extraordinary players.
``They have the ability to get through to the Champions League semi-finals.''
