Kieran Tierney seemingly offered to meet Cucho Hernandez after Arsenal's win over Watford as the pair were involved in an altercation at Vicarage Road.
The Gunners secured a 3-2 win over Roy Hodgson's men as they boosted their top-four aspirations with a vital three points.
Mikel Arteta's side were seemingly in cruise control in the second half as Gabriel Martinelli's second-half strike gave the visitors a two-goal cushion.
But Moussa Sissoko grabbed one back for the hosts as they made a late surge for an equaliser.
Arsenal were able to hold them off, however, as the north Londoners used their newly-found street smarts to wind the clock down.
Watford construed it as time-wasting and were not happy with their opponents as tempers flared in stoppage time.
What do you make of Kieran Tierney's confrontation with Cucho Hernandez ? Comment below
Cucho Hernandez, who scored an acrobatic equaliser in the first half to cancel out Martin Odegaard's opener, tried to get Arsenal to speed up proceedings by forcefully putting the ball in Tierney's hands for a throw-in.
Tierney exaggerated the contact, falling to the ground briefly, which led to a coming together between both sets of players.
Hernandez was furious as he felt Tierney was guilty of diving.
Arsenal players tried to defuse the situation but they couldn't calm down the Watford man.
The Arsenal left-back then got back up and signalled to Hernandez that he would meet him after the game to settle the dispute.
Hernandez backed down and walked away from Tierney, as a result, as play restarted with Arsenal seeing out the victory.
Mikel Arteta had a hand in Martinelli's goal that proved to be the match-winner for the Gunners.
The ball went out of play on the right-hand side for an Arsenal throw-in and the Spaniard rushed out of his dugout up the touchline to give the ball to Bukayo Saka quickly so the visitors could spring a quick attack.
And it worked to perfection as Saka got the ball back in play quickly to Cedric Soares who played it inside to Martin Odegaard.
It was all one-touch stuff from that point on as the Norwegian then found Alexandre Lacazette who laid it off for Martinelli who rifled it into the top corner past the helpless Ben Foster.
Asked about his decision to play ball boy, Arteta said: "I saw the ball there and saw an opportunity to take advantage.
"I don't know if I should have done it but that is the way I live the game and I couldn't help myself."
