This is a very high odds, only williamhill and eurobet has it, other bookies have around 2,10 for the same bet!
I believe that it can be another game with many goals when benfica plays at home, lika we are used to this season. They won last home game in European league 4-0 against H Berlin, Marseille have two 3-1 wins in this european league R32 round against Copenhagen. Marseille only has defender Gabriel Heinze injured for this game, Benfica has no important injury here what i can find.
I bet over 2,5 goal to 2,20 in odds great!
