N Lapentti is more experienced player on clay. He real fighter, and can do damage to most of players on clay when he motivated. He is stable from the baseline and good returner, also his combinations are dangerous espesially for players whose footwork are not. So if somebody give Lapentti a finger he can bit an arm xD.
Daniel is a powerplayer who really depends on his serve, and powerfull attacks. But his style suits to Lapentti. It wiil be more hard to beat Nicolas because with this type of players Daniel always played badly, badly against perfect baseliners, because Daniel unstable in long rallies, very often long rally ends by his unforced error. So this is the key match in meeting, Lappenti has no chances for mistake, and everything depends on him.
