3. Andy Murray
Andy Murray is undoubtedly one of the best players in the world right now, but despite that, he is still one of the players we believe you need to watch out for. It took him a while but now he's finally won his first two Grand Slams, it is ridiculous to say that it isn't obvious he's desperate for me. With the backing of his family and coaches - in particular, former world number one, Ivan Lendl - he has an unbelievable chance to further his Grand Slam title count. Murray's class is evident, his consistency with groundstrokes and the pace of his transition from offence to defence just amplify that. It is clear to see why he is the current Olympic Champion.
