I used to think he was a big ******* last year or so. However, this year I have heard him being critical of Nadal. Several times, not once, he has brought out how much time Rafa takes between serves, that it exceeds the recommended time, and compared it to Fred.
Of late, he's been complementing Fred a lot. I think he's okay.
Also, Lahyani has made a lot of good overrules. One mistake today should not invalidate his correct overrules. As far as Lahyani being a *******, I've heard Fred arguing with him and once being rather rude, I dont think he'd continue being a Fredtard after that.
I think he's fine too Senti, great commentator. But where does he get that Laayani was in favour of Federer? I mean, the match with Nadal callwise was hardly any controversy
