Cristiano Ronaldo and Maurizio Sarri appeared to engage in a touchline spat during Juventus ' International Champions Cup clash with Tottenham on Sunday.
The Portugal international was substituted moments after putting the Italian giants 2-1 ahead against Spurs, and it seems that this rubbed him up the wrong way.
Video footage, which is widely available on social media, shows Ronaldo walking off the pitch after his number is called and shaking hands with a Juventus coach.
He then walks past former Chelsea manager Sarri and utters something but fails to stop, leaving the Juventus boss standing on the touchline looking sheepish.
Fans took to Twitter to suggest that Ronaldo was upset about being hooked so soon after scoring, despite the fact the match was just a friendly.
Tottenham came from behind to beat Juventus at the Singapore National Stadium after initially taking the lead through Erik Lamela.
A quick-fire Gonzalo Higuain and Ronaldo double put the Old Lady in the driving seat before Lucas Moura replied with an effort on the 65th minute to draw the scores level.
Spurs had to wait until stoppage time to for the decider, but it was well worth the wait.
Harry Kane struck from near the halfway line, catching former Arsenal keeper Wojciech Szczesny completely off-guard to win the match for Tottenham.
