## Playing style

Niculescu is a right-handed player, known for her unorthodox style of play. Her trademark is an unpredictable forehand slice. She enjoys hitting a flat, two-handed backhand. She is able to force tricky drop shots and precise volleys. During her match against Johanna Konta at the 2017 China Open, Niculescu showed a variety of spins.
Niculescu cited Martina Hingis and Andre Agassi as her tennis idols. Her opponents have not always enjoyed playing against her, since her playing style is opposite to what most players do. For instance, she hits a slice forehand, but she hits a topspin backhand. One tactic Niculescu uses to break through her opponent's defence is to force her opponent to run more by using her footwork.

## Coaches

She is currently coached by Călin Stelian Ciorbagiu.
