I see myself as a tennis fan, but couldn't give a toss about the Davis Cup.
Difficult to hypothesise, but I reckon I would support Murray, even if he wasn't British. It's great to see someone putting every ounce of effort in to bettering themselves. Those internal battles that used to ruin his gameplan. Making sure he was one of/the best at scurrying around the court.
Yeah even though i'm not really a fan of him, his performance today was very good can't fault him on that
