Ronaldo cops fine for celebration gesture

Juventus forward Cristiano Ronaldo has been fined 20,000 euros ($A31,940) by UEFA for appearing to make an obscene gesture while celebrating his side's Champions League victory over Atletico Madrid.

The Portugal international was guilty of "improper conduct," the control, ethics and disciplinary body of the European football organisation ruled on Thursday.

Ronaldo had gestured to his crotch following the final whistle after his hat-trick earned Juventus a 3-0 win over Atletico on March 12 which sent the Italians into the Champions League quarter-finals 3-2 on aggregate.

The gesture appeared to be a response to Atletico coach Diego Simeone, who had celebrated in similar fashion during his team's 2-0 win in the home leg.

Simeone was subsequently also fined 20,000 euros by UEFA.
