#4 Gael Monfils
Gael Monfils is another player who hasn’t done justice to his immense talent. The Frenchman won the Rotterdam Open in February and was a quarter-finalist at the US Open this year.
His athleticism has always been outstanding which makes him a treat to watch any time he is on the court. When he is on song, his sublime baseline game is good enough to unsettle his opponents. Monfils's brilliant groundstrokes during the run of play and his exceptional dropshots make it difficult for his rivals to read his play.
Monfils can also cover a lot of ground with his reach and quick moves. The 33-year-old's fast serves are also a big weapon for him which will make him dangerous on the fast courts at the China Open.
#5 Fabio Fognini
Fabio Fognini is one of those players who can pack a punch when he is in his prime. It is surprising why he has not been able to make his mark given the talent he possesses.
The Italian won the Monte Carlo Masters this year in April for his maiden ATP Masters 1000 triumph. Fognini underlined his talent further in that tournament when he beat Rafael Nadal in the semi-finals.
The Italian can bring a surprise element in his game due to his unpredictability. The 32-year-old is quite good with his deceptive dropshots and can be a tricky player at the net. He has also shown his sharpness with his highly accurate baseline game when he is feeling confiden
His forehands can also make a lot of damage especially on clay and hard courts, which is why he should be very much considered among the potential winners of this ATP 500 tournament.
