They won't try to influence the referee. That would be too obvious.
However any referee already knows who FIFA want in the finals. They won't try to be corrupt but will know their own world cup chances won't be helped by a win for the less favoured team particularly if they fail to give a penalty if there is any doubt. They won't be penalised however for giving a penalty for a Ronaldo dive.
Although Hiddink's Russia aere far superior to France or Portugal they'd probably be a better team to draw. Greece are definitely the best though as FIFA won't care who wins.
