Match of the week: Marseille-Lyon (France)
Lyon's 3-0 win at Nantes on Tuesday could not have sent a clearer message to the boys in Marseille: it's not over till it's over. A win for OM would leave them firmly on course for their first Ligue 1 prize since 1992, but an away success would open up the title race. A Lyon upset returns 70 points, while a home win is worth 57 points.
The derby: Copenhagen-Brondby (Denmark)
The Copenhagen Derby, as it so often has, could have a big say in the destination of the trophy. Second-placed Brondby trail leaders Copenhagen by just two points with four rounds remaining. Chasing a first league crown since 2005, Brondby would go top with victory and earn their backers 82 points.
The long shot: Manchester United-Arsenal (England)
The Gunners will seek to avenge their UEFA Champions League elimination at the hands of the Red Devils. With Andrei Arshavin available and United having one eye on the continental final in Rome, they will be confident of an upset.
Too close to call: Atletico Madrid-Valencia (Spain)
This La Liga match could very well decide these rivals' European fates for next season. Fourth-placed Valencia are one point clear of fifth-placed Atletico, and fresh from a decisive 3-0 win at Real Madrid. Los Colchoneros, however, have lost only one of their last six home games, making them slim favourites at 43 per cent.
Atletico Mineiro-Gremio (Brazil)
After losing 2-0 to Gremio back in December 2008, Atletico have the opportunity to claim a home victory of their own in the Brasileirao. Gremio are the favourites at 54 per cent to win, despite having lost four of their last six away fixtures.
Urawa Red Diamonds-Gamba Osaka (Japan)
In the J.League 2009, Gamba Osaka have only managed two wins in their five away matches thus far, while Urawa Red Diamonds have lost only one of their five home games. The Reds enjoy a 50 per cent chance of victory on their home turf in Saitama.
Results will be published on Monday, along with the fixtures for the penultimate round of this season's FIFA World Leagues Predictor.
