England's Under-21 side stormed to a 5-0 victory over Lithuania in Tuesday evening's Euro 2015 qualifier, but the goals were overshadowed by a spat between Wilfried Zaha and Ravel Morrison.
As an England attack broke down, the Manchester United prodigy and the West Ham star—who had already scored a wonderful solo goal—engaged in fisticuffs for some unknown reason, only to be broken up by Norwich's Nathan Redmond. The Telegraph reported that the argument might have been over Morrison not getting a chance to take a penalty and complete a hat-trick.
Ravel and Wilf are by no means the first teammates to fight one another, but they lead our list of players who should know better...
Here's the footage of the aforementioned England youngsters forgetting that they should focus their aggression on the opposition rather than each other.
During his career, Graeme Le Saux was painted as a cultured soul who preferred broadsheet newspapers and antiques to lad's mags and lager. But this haughty reputation didn't stop him from tangling with Blackburn team-mate David Batty during a Champions League match with Spartak Moscow in 1995/96.
Graeme, if you're going to fight anyone, try not to pick the hardest player on the pitch.
While at the West Ham training ground in September 1998, John Hartson felt Eyal Berkovic went down a little too easily from a tackle.
The striker attempted to pick him up, but the Israeli lashed out, obviously feeling aggrieved. He probably felt a little more aggrieved after Hartson kicked him in the face.
While losing 3-0 to Aston Villa in April 2005, Newcastle's Lee Bowyer decided the best course of action would be to start a fistfight with teammate Kieron Dyer.
Both players were sent off, but Bowyer received a fine of £30,000 from the FA, a fine of six weeks' wages from his club and a £600 fine in court under the Public Order Act.
In summation, it was an expensive first punch to throw.
When the final whistle blew after Bayern Munich's 3-1 demolition of Werder Bremen in January 2011, Die Roten's players should have been in a joyful mood.
Arjen Robben, however, took exception of Thomas Muller's apparent criticism of one of his wayward free kicks and did some angry talking with his fists.
Arjen Robben is an angry little man, isn't he?
The Dutchman didn't appreciate Bayern Munich demigod Philipp Lahm tackling him from behind during a training session in 2010, and they had to be separated.
Lukas Podolski failed to see eye to eye with Germany captain Michael Ballack during a 2-0 win over Wales in April 2009, so he gave him a slap.
Poldi was reported to the police for the seemingly innocuous incident, but the DFB took no action against either player.
During the Merseyside derby of 1993/94 at Goodison Park, Bruce Grobbelaar became incensed with Steve McManaman for a dodgy clearance. The goalkeeper shoved him in the face, but Macca gave back as good as he was getting.
Unless you follow Lithuania's top flight, you may not have heard of Titas Vitukynas and Deividas Padaigis.
Just last week the FK Dainava Alytus defenders were shown red cards for brawling with each other in a 1-0 loss to Banga. The fight is made much more dramatic by the '80s cop-show music on this clip.
Unfortunately, we have no idea who these Iranian teammates are or the name of their team, but we do know they were both shown red cards for this Persian punch-up in January.
