Bernard Tomic and Nick Kyrgios may have to improve their behavior on and off the tennis court if they hope to represent Australia at the Rio Olympics.

Both players have been put on notice by Australian chef de mission Kitty Chiller, who described Tomic's behavior at a tournament in Madrid this week as "appalling," after he deliberately gave up a match point — with the handle of his racket facing forward — and later said he didn't care because at the age of 23 he was already worth $10 million.

Kyrgios has been fined and given suspended bans over his on-court behavior in the past.

Chiller said at the AOC's annual general meeting Saturday that "there's a few athletes that are on watch and those two names are among them."
