Luis Fernandez has been caught on Spanish television goading Sevilla players and shouting at Juande Ramos to watch out for flying bottles during Real Betis' Copa del Rey game on Tuesday evening.
The Betis boss allowed his frustrations to boil over as his side bowed out of the cup after failing to score in the 33-minute mini-match that was played behind closed doors in Getafe.
Sevilla striker Luis Fabiano was targeted by Fernandez, who reminded the Brazilian about his fight with Real Zaragoza's Carlos Diogo in January.
"That's the boxer, he's the one that fights," Fernandez barked. "Hit him hard. The number ten likes to box. Just like he did with Diogo."
Next up for a tirade was the unfortunate Ramos, who was knocked unconscious at the end of last month by a bottle thrown from the crowd.
"Watch out for another bottle," Fernandez was seen shouting at his opposite number.
Frederic Kanoute's goal in the 57th minute of the second leg on 28th February was followed by Ramos being knocked out and the game being abandoned.
The Spanish football authorities ordered the final 33 minutes to be replayed at the Alfonso Perez this week with the score standing at 1-0 to Sevilla on aggregate.
With no goals in the final section of the game, Betis were eliminated, something which evidently proved hard to take for Fernandez.
Ramos refused to comment about the incident and Sevilla president Jose Maria del Nido said: "One of the unwritten rules of football is that what happens on the field stays on the field.
"If Juande does not want to talk about this then I am not going to make him."
Real Betis forward Edu was not so impressed with his coach's actions as he added: "The only ones that are hurt by all this are the clubs, if not the city as a whole."
