Blatter angry about Berlin brawl
FIFA president Sepp Blatter is 'furious' with the on-field violence which followed Germany's penalty shoot-out victory over Argentina in Friday's World Cup quarter-final in Berlin.
At least one German player was left lying on the grass after being kicked while there was also widespread punching and pushing following the end of the game.
Relations had soured during the shoot-out itself and spilled over at the end as players and officials from both sides clashed, and Blatter confirmed FIFA's disciplinary committee would investigate.
'I am furious about that and our disciplinary committee will monitor this incident and definitely will take some steps towards those who are identified as being the `provocateurs' of this incident,' he told BBC Radio Five Live.
'There was really no need. After 120 minutes football is a drama, and then you have to go to penalty kicks and then football becomes a tragedy, but one is the winner and one is the loser.
'What I always say is in football you learn to win, but you also have to learn to lose.'
Argentina's Leandro Cufre, an unused substitute, was shown the red card by referee Lubos Michel for his part in the melee after he was seen kicking Germany centre-back Per Mertesacker.
Mertesacker told PA Sport: 'They are no choirboys, that's for sure.
'One of their players attacked me even though I did not do anything, and he got the red card. I have three or four red marks on my thigh and then he kicked me again in the groin.
'I cannot understand that it turned into so much aggression. He behaved in a very unsporting way and I asked him why he did that and then he completely lost it again.'
German team manager Oliver Bierhoff, caught in the middle of the melee which immediately followed the penalty shoot-out, said he had intervened after seeing Mertesacker targeted.
Bierhoff said: 'Per was angry about what was a very unsporting thing to do and the players started going at each other. I saw that and wanted to put myself between them so the players didn't do anything stupid.'
