As the holiday season approaches, competitors need to keep their cool if they want to make their mark in FIFA World Leagues Predictor. takes a look at some of Round 15's big games.  

Last man standing

Fluminense-Guarani (Brazil)
The final matchday of the 2010 Brasileiro includes a fixture between two teams currently enjoying contrasting fortunes. Hosts Fluminense will claim the league title if they win today no matter the outcome of the Goias-Corinthians encounter. Guarani, meanwhile are on the other end of the spectrum, having already been consigned to relegation. Will they go down meekly or exit the top tier with heads held high after derailing the title front-runners?

Outside looking in
Manchester City-Bolton Wanderers (England)
Currently perched on the outskirts of the European places on the Premier League table, Bolton Wanderers have the chance to close in on fourth placed Manchester City when they visit the City of Manchester Stadium on Saturday. The visitors have lost only two games this season, a record bettered only by Manchester United, who have gone 15 games without defeat.

Strugglers square off
Schalke-Bayern Munich (Germany)
Like Schalke, Bayern Munich have suffered a disappointing start to their Bundesliga campaign, the difference being that the defending champions looks to have pulled themselves out of the more while Felix Magath's team are stuck in 15th place. Of the 80 league games between the pair, Schalke have claimed 17 wins and Bayern 38; the two teams have drawn on 25 occasions. Bayern’s last visit to Schalke back in April ended in a 2-1 victory for the visitors, but what will Saturday bring?

Pride and place
Shimizu S-Pulse-Gamba Osaka (Japan)
The final matchday of the J-League season is somewhat academic, with Nagoya Grampus Eight already assured of the title. However, Gamba Osaka will still be fired up for a win, which would ensure them an AFC Champions League qualification place. A Gamba win could also potentially see them finish runners-up. Will fifth-placed Shimizu disappoint the silver medal hopefuls?

Serbian showdown
Crvena Zvezda-Vojvodina Novi Sad (Serbia)
Fans in Serbia are set for for a battle in the upper echelons of the Superliga. Second-placed Crvena Zvezda host Vojvodina Novi Sad, currently third, with only three points separating the pair. The hosts are favourites, but a Vojvodina surprise could return over 80 points for backers.
