Nick has the most 'untapped potential' of the current Aussie players,his loss of focus in matches is a big concern.If he wants to move up the rankings he has to address this problem ASAP,he also needs a coach to keep him on the straight and narrow,though that will be up to Nick to respect his new coach,he is a free spirit,which I have no problem with,though it would be a shame to see him not living up to his potential.
Daria is a very passionate player on court,again I have no problem with that at all,expect it does cost her in 'crucial points on court'.My concern with Daria is her serve,she needs to address it and work on it,lately she has been prone to injury.She has a great coach in former Aussie player Nicole Pratt,
Tomic needs a proper coach,not his hitting partner.Tomic's dad is now overseeing his daughter Sarah Tomic.To me Tomic has not evolved as a player,he is still playing the same tennis when I watched him as a junior.He should have a better serve,he is a tall player,his movement can also be improved.If Tomic wants to move up the rankings he has to add a bit more variety to his game.For example moving forward to the net,he needs to work on his transition game.Even the top players are always working on their games.
