That is not even close to an educated guess...
Madrid have won each of their 4 group games and a positive result will ensure they progress to the knockout stages as group winners.
Basel, though, won't make things easy for the European champions - Paulo Sousa's side have won both of their home games in the competition and are unbeaten in their last 8 competitive matches at St. Jakob-Park.
This will be tough for Madrid, but they are in irresistible form at present and should secure victory in this one.
