He's really fit is Murray and has got a lot of class.
But there are players fitter and classier.
He needs to go away and work on his physique more.
It's just that little extra power in his shots and that little bit more stamina that would see him become a champion.
Otherwise, he will never win a major.
He is naturally gifted but hasn't got the body at the moment.
And I am not sure a cardboard cut-out as a coach helps.
It is clear when players are not throwing the ball high enough on first serves, that's when a bit of coaching wouldn't go amiss.
