It was a good performance from Kohli - he really does have some flash in his game when he's playing well and a lot of it was on display today once he got over his initial nerves.
yes he seemed a little intimidated by the stadium (or the crowd) at the beginning of the first set and got broken early. but after 15-20 minutes he got into his groove and by the second set he's been in what lleyton usually calls "the zone".
but i'm happy he's done it in 2 sets, because he's definitely playing top level during that set. don't know if he can play like that constantly.
