He needs to see the psychologist Andy saw to help stop him from being distracted by off-court matters, of which, unfortunately, there seem to be quite a few. Separation from his father's influence might help too.
That sounds like a really good idea - it could help him focus during matches. Aside from his self-inflicted bad behaviour, it can't have been easy dealing with all the negative press coming from Australia and the pressure of expectation for him to be another Lleyton/Rafter. Though I see he's said he was suffering from the flu today, so perhaps illness was a factor in his poor performance.
Really impressed by how well Gimeno-Traver is playing at the moment - could we be in store for another top 8 upset?
