Paris St Germain boss Carlo Ancelotti believes victory against Rennes tomorrow could be the key to winning the Ligue 1 title.
PSG are seven points clear of Marseille at the top of the table with eight matches remaining, leaving the Parisians close to winning their third championship.
Rennes are 10th in the table with no threat of relegation and eight points off a European spot and although Ancelotti was keen not to undermine any upcoming fixtures, he conceded this one could be more important than most.
``We must manage our seven-point lead and win the game tomorrow,'' he told reporters in the pre-match press conference.
``All games are important, but tomorrow may be the key to winning the championship.
``We must give all possible energy to win the game in Rennes. They are a very tough team.''
Despite Wednesday's Champions League quarter-final first leg clash with Barcelona and the corresponding fixture this week, Ancelotti will not be tempted to rest his key men.
``I will not change much tomorrow, the players have recovered well,'' he added. ``Tomorrow I will put the best team to win.''
Their opponents come into the match without a win in five, but boss Frederic Antonetti is confident his side will soon find their form.
``It's been a month and a half that we do not have results,'' he said on the official Rennes website.
``We are working to resolve the issue. We must adjust the small details that will get us out of this bad run.
``We are not resigned, if you watch the games, you can see that this is not the case.
``Mathematically, we still have much to play for in this league.''
Midfielder Alou Diarra, who is on loan from West Ham, says his side will be motivated by the opportunity to play such an impressive team.
``This is the kind of game that all players like to play in,'' he said. ``We will face the best team in the league. They have world class players. They compete with Barca. It has become a high-level team.
``They do not have enough room to overlook the championship. They play in the Champions League on Tuesday. But they have the strength to do rotations.
``Whatever the Paris team this Saturday, it will be of very high level.''
