Jude Bellingham absolutely tore into teammate Nico Schulz after a poor pass, calling his Borussia Dortmund teammate "f***ing s***" during their Europa League exit.
The England star's verbal volley came during their 2-2 draw with Rangers in their entertaining clash at Ibrox on Thursday night.
The Scottish side triumphed 6-4 on aggregate after a dazzling display at the Signal Iduna Park which saw them run out 4-2 winners.
Dortmund could not muster up a comeback in Glasgow on Thursday night though, succumbing to elimination.
But it was not for the lack of trying, certainly on Bellingham's part, who ended the night as his team's most important player with a goal and assist.

However, late on the 18-year-old was left frustrated with his teammates when he received a poor pass from left-back Schulz.
The teenager had surged forward and demanded the ball but it was just slightly behind from the German, sparking a furious rant from the midfielder.
Cameras picked up Bellingham's reaction and he could be seen screaming at Schulz: "You can't get one f***ing pass off, you're f***ing s***. Every f***ing time."
It was a fierce moment from the youngster, who had tried all night to rope his side back into the match despite their terrible start in Glasgow.
After James Tavernier opened the scoring from the penalty spot, Dortmund looked down and out.
However, Bellingham equalised soon after to restore some hope for the Bundesliga outfit before assisting Donyell Malen nine minutes later to take the lead.
Tavernier would grab another, though, to complete a brace and all but end any chance of a comeback from BVB.
It tops off a shoddy campaign in Europe this season for Marco Rose's men, who crashed out of the Champions League group stage and had been tipped to go far in the Europa League.
As well as being thrashed by Rangers, Dortmund were on the wrong side of a hiding from Ajax and Sporting as well earlier this season.
What it means for the top youngsters at the club remains to be seen but it will do nothing to persuade the likes of Bellingham and Erling Haaland that their futures are best served in the Ruhr.
Liverpool and Manchester United have been interested in the former Birmingham City ace and both clubs are in the market for a midfielder this summer.
Dortmund have proved in the past, though, that they are tricky negotiators and held onto Jadon Sancho for an extra season despite attempts from the Red Devils to snap him up.
They did lose the England international in the end for a sizeable chunk less than the original £109m that had been offered with the winger moving to Old Trafford for £73m.
