A surprise maybe not. Lendl has been there and both worn and won the tee-shirt and I enjoyed watching him also. Andy has thought this strategy through and I feel they are both in it for the long haul not a quick fix. Lendl likes Andy's game,this is a plus. All positive vibes now Murraysworld. Best news have had this year!!!
The announcement couldn't have come at a better time!
I'm just relieved that, after all these months and much speculation on MW, Andy has found what I hope is a permanent coach. All this fiddling around, trying to go it on his own, etc, was never going to work, and neither was having Cahill or other Adidas coaches on a piecemeal basis. Andy certainly can't be accused of rushing into this, and I'm sure that as Lendl was training with him in Miami the pair of them have a fair idea as to whether the relationship has a good chance of working or not. As you say, Andy wants somebody for the long haul now.
I'm sure one thing that greatly appeals to Andy is that Lendl had a reputation as a workaholic, and Andy is known to be one of the hardest workers in the game. I just hope Lendl can get inside Andy's head and help him with the mental side of things, but if Andy has the hunger to win a Slam, then I'm cautiously optimistic that Lendl just might be able to take him up that one crucial step further. So Lendl won't stand for any of Andy's nonsense? Well that's up to Andy if he wants to keep Lendl as his coach, and I do believe from what we saw of Andy in the Far East that there is a work in progress with this, probably due to Cahill's influence - Cahill being a strict believer in self-discipline on court.
Also an improvement in his serve and more power in his groundstrokes certainly won't go amiss, and neither will honing his ruthless streak (but please, not to the extent where he knocks players off their feet, as Lendl did!). What I don't want is for Lendl's lack of finesse to rub off on Andy. Being a power-house is one thing, but I'd hate to see Andy's delicate touches done away with since they're what make his game so unique. To me, power without finesse is nothing, and it's boring to watch. Andy apart, that's the difference between Federer and Nadal/Djokovic.
PLEASE though - don't expect miracles overnight! Like all tennis partnerships it'll probably take a few tournaments before the benefits show. Andy may not win the AO, he may not even get to the final, but I'm damned sure that Lendl won't allow him to disappear into a black hole like he's done the last two years.
