Here is an article in German, nothing new, but it sums up pretty well what happened:
The journalist describes the press conference and stresses one more time the change of tone in Philipp's statements, while he's had some truly embarrassing post-match interviews in the past.
This time he was spot on and analyzing very well what he had done wrong. He saw in the 5th set that Verdasco was struggling at one point. Not for a long time, just 5 minutes. But he says he was feeling very tired himself at that point and couldn't use the opportunity. It was doubly painful because he could see there was a chance, but his shots were not hurting Verdasco anymore. The reason in his opinion is that he had been a bit sick in the days before the tournament/the match.
Then follows a detailed match report, the story with Verdasco's foot with the medical time-out in the mdidle of a game. Wilander apparently said in the Eurosport daily summary that it "was too much drama for his liking". Verdasco was looking in terrible pain and then in the 5th he was moving normally again. Maybe the pain killers worked very well. Maybe he had overdone it a bit too.
Too much drama from Verdasco. But not enough drama from Kohli. No fist pumping, nothing. Verdasco was pumping himself up like crazy when he won a point, lamenting after every miss. A lot of antics, but nothing unfair.
Whatever he might say, Kohli should have tried more at the beginning of the 5th set when he saw the chance, even if he was feeling tired. He's lacking the "killer instinct" and the match exposed his main weakness.
