I like this bet. Berdych should beat Monaco, Czechs should win the doubles match even though it's pretty balanced and let's say the rubber that will decide this tie will be the one between Berdych and Del Potro. Normally, i think Delpo should win this judging the support of the crowd which will be amazing but he said he's not 100% (didn't he?) and he's carring an injury which could trouble him very much.
Nothing sure but i think i'll take it too with small stakes
Berdych will play against Berlocq instead of Delpo in the 4th rubber so it's almost a sure win on Czech Republic
