These days, increasingly the referees and match officials are subject to players frustration. Many times players are just let off by simple warning. I feel this needs to be stopped as many players are heroes to too many aspiring to be atp tennis players and such behaviour can influence them negatively.
Who among the new generation of players can be compared to the big 3 (Novak, Rafa and Roger) in terms of their personality and playing style?
