LONDON (Reuters) - Stan Wawrinka believes he can overcome not just a great friend and supreme champion in top form but also a crowd willing him to be beaten by their beloved Roger Federer at the ATP World Tour finals on Saturday.
Wawrinka and Federer will team up next week for Switzerland in the Davis Cup final against France in Lille but for one night before that in London’s O2 Arena, they will be fighting each other in what Federer calls an “historic” game for a place in Sunday’s final of the end-of-season classic.
