Thibaut Courtois ticked off Chelsea teammate Eden Hazard during Belgium's 6-0 World Cup qualifying win against Gibraltar on Monday.
Belgium have scored 13 goals without reply in their first three games of the campaign to put them in a strong position in Group H, but Courtois was upset by Hazard's showboating which he felt put his clean sheet at risk.
"I think I made my best save of the last two matches today," he said. "You always have to be alert. That's what I did, the team too. It's good to win like that.
