He catches like he does for the sole reason of keeping defenders away from him, one was bound to go wrong. He did kick him in the face, he should have been suspended, and he probably shouldn't catch like that any more. Not that it is illegal, but that it is dangerous. For defenders, as we seen, and for himself. If he comes down on one leg wrong, he could well end up like poor Yow Yeh last year.
Still, saying he deliberately seen the player coming and extended his leg is ludicrous. No-one, i don't give a sh*t who you are, can react like that in real time. He is not in the freaking matrix. Even F1 drivers don't have that sort of a reaction speed. If you slow it down enough, yeah it looks like he seen Klemmer and extended his leg. In real time, he looks at Klemmer and extended his leg in all of about a half a second.
It WAS deliberate, in that it is his tactic for defusing kicks, and one was going to go wrong.
It WASN'T deliberate, in that he seen the player coming and thought "I'm gonna kick this guy in the face."
