I think he was a little bit pissed off about this serve which could have been an ace to draw even at 6-6 in the tiebreak, but from the crappy replay they showed, my feeling was more that it was "out" than in.
Then, I also found the little discussion with Lahyani funny the way Kiefer approached him and told him "did you see the chalk coming up?" and then Lahyani "nonono, there was no chalk!"
I also think Kiwi made this up or it was wishful thinking, but I also didn't see the chalk in the replay or in real time. But that was great.
Also did somebody clearer understand what it was that Lahyani told Kiwi in the third set two times? At the beginning of the 3rd, I think it was 2-2 he said something like "oops! Nicolas, you didn't want to more." I'm not sure I understood it correctly, but there must have been something because the crowd even laughed about it. Was it that the ballkids threw unwanted balls to Kiwi while he already turned his head away from them?
I just don't know because they showed Djokovic during this situation.
The next scene was as Lahyani said something like "keep going"? Did he mean Kiwi was too slow on serve or what was it? Somebody remembers these two scenes or knows better what was going on there? Would be interested to know!
