Even though Kohli is 5 years older than Delpo, Juan (IMO)has the stronger mind control. Even at 22, he seems to have stronger mind control than almost everybody he plays, regardless of their age.
In a way it's too bad that Kohli's new coach (for about six months or so) is the same guy who was coaching andy murray when andy beat juan x3 on hard and x1 on indoorhard ... tho juan beat him on the clay in 2009 ... what i'm saying is that kohli's coach would have told him how best to beat Delpo.
otoh, knowing how to beat someone and actually beating him are two different things. of course, Kohli just beat another big server with a flatish forehand in soderling, but he also has a history of beating soderling .... his history against delpotro, otoh, is a losing one of 0-2
I will enjoy watching the kohli groundstrokes, but I also have faith in the 22yearold ..... vamos delpo!
