Liverpool left-backs Andy Robertson and Kostas Tsimikas found themselves in a heated exchange while on international duty.

The defensive duo parted for the international break to join their respective national teams, Scotland and Greece, and were swiftly reunited on the field as their countries locked horns in the Nations League.

Scotland journeyed to Piraeus to face the first leg of their Nations League play-off clash on Thursday, with the aim of staying in League A and avoiding relegation to be taken over by Greece, who took second place behind England in League B Group 2.

Despite having fewer shots and controlling less of the game, Scotland secured a 1-0 lead courtesy of a first-half penalty from Scott McTominay.

However, Tsimikas seemed to take issue with Robertson's reaction, appearing to exchange words with his Liverpool colleague off-camera – which prompted the Scot to angrily point at his captain's armband in defiance.

Social media platform X saw fans striving to decode Robertson's words to his teammate, with one attempting lip-reading and suggesting: "No love lost between Robertson and fellow Liverpool left-back Tsimikas.

'Because I'm the f------ captain, Kostas, outside.'"

Another fan chimed in: "A canny be sure exactly what Robertson is shouting at Tsimikas, but it includes "...because am the f------ captain..." A third echoed these sentiments, stating: "I thought the same live!"

Robertson marked his 80th cap for Scotland on Thursday night, having celebrated his 31st birthday earlier this month.

Robertson and Tsimikas are rivals for the left-back spot at Arne Slot's Liverpool.

I think I've had a relatively good season but one thing people will say about me is that's I've been pretty consistent, so when you make a couple of mistakes, then people can talk.
