Well, after to watch that poor final the younger players definitely have to improve a lot more mentally. According what Novak said he has a muscle tear in the oblique but his service was better than ever and nothing in his game looked he had that problem. Definitely he knows how to act and to work psychologically like he did playing vs Fritz when he felt that he could have lost the match. There is something very clear, others players when have had a muscle tear or they have lost or they have had to retired. Sorry but I don't believe him and its sad that he still likes to draw on to those tricks
