The feud between former Liverpool stars Fernando Torres and Alvaro Arebloa continued with another touchline spat at the weekend.
The pair spent two-and-a-half years together at Anfield under Spanish boss Rafael Benitez.
But now they are youth team bosses at arch rivals Atletico and Real Madrid.
Torres is now the manager of Atletico Madrid's famed Juvenil A squad, while Arbeloa is in charge of Real Madrid's U19 side.
And things got heated when their teams met in the 'mini derby' on Sunday, with Torres’ side claiming a 2-1 win.
While Torres celebrated the result with his coaching staff, footage from Marca showed that Arbeloa did not hang around to shake hands with his opposite number, briefly waiting before heading to the dressing room.
Arbeloa was unaware of the drama after the final whistle as rivals players squared up to each other on the opposite side of the pitch.
It comes after Torres was shown a red card for threatening Arbeloa during an U19s game in May.
Things got heated between them when they squared up on the touchline.
And as shown by footage online, Torres, 39, was sent off for confronting and shoving his compatriot.
After a flare-up on the pitch, former defender Arbeloa approached the iconic former striker, clearly angry and gesticulating.
Torres, who has bulked up considerably since his playing days, then gave the 40-year-old a shove, saying 'I'll blow your head off'.
Arbeloa then responded: 'Start whenever you want.'
The referee showed Arbeloa a yellow for his actions, before giving Torres his marching orders, to the delight of the home Real crowd.
Footage then shows several furious Atletico players and coaches storm onto the pitch to confront the official.
The game finished 2-2 after extra time, 4-2 to Los Blancos on aggregate, sending Arbeloa and Co through to the Youth Cup semi-final against Las Palmas.
