Watched a bit of Game, Set and Mats last night and for once Mats put his finger on it I thought when he said Andy looks like he's really enjoying his tennis again, which he didn't so much under Lendl. Now that might not be to do with Lendl but could be that for the first time for ages he's playing without pain and his body is feeling really good. And I think that is releasing him to play with the combination of aggression and flair that makes him unique. And I think Amelie is the perfect coach to release that in him. I'm not sure Lendl really appreciated the flair side.
I agree with this Ruthie, last year (most likely because of the struggles he was having with various factors) he looked pretty miserable and he was not enjoying himself out on court. It was clear that Lendl is what Andy needed at the time when he joined in 2012 and they had fantastic success together, but people and situations change, players needs and wants change as well.
Andy really does look like he is relishing being out on court right now, the joy is there, the hunger is there and the fight is there. I finally managed to catch up on the match last night having only seen the first set before it went to a tie break, and thought Andy showed a great deal of mental strength, he had that 'steel' about him.
The on court interview was quite emotional for him. Thought Jim Courier handled it quite well and really let Andy express himself. It was obviously an emotional moment for Andy's team as well. David Law from Radio 5 Live reported on Twitter that there was a massive hug between Andy and Amelie backstage when he came off the court.
