"I did not do it on purpose, we both tried to catch the ball and we hit each other. I apologise, it can happen in football." - Zlatan Ibrahimovic.
Somewhat predictably, Swedish striker Zlatan Ibrahimovic dominated the Milan derby, winning the match with an early penalty against his former club with whom he had so much league success.
One of the sub-plots of the match was Ibrahimovic's battle with veteran Nerazzurri defender Marco Materazzi, as the pair have had an up and down relationship now for a number of years.
Whilst at Juventus, Ibrahimovic was the victim of a number of poor challenges from "The Matrix" - video evidence here and here:
When the pair were at Inter together, they became good friends, however when Zlatan left for Barcelona, Materazzi took it badly and saw it as a betrayal. Since the Swedish striker has returned to Italian football, relations between the pair have reportedly been frosty.
The match started with Materazzi committing a poor foul on Ibrahimovic in the box to give the Swede the opportunity to win the game from the spot.
In the second half with Inter chasing the game, Zlatan sent Materazzi to hospital with a kung-fu kick. After the game, Rafa Benitez played down the injury saying it "doesn't seem serious".
Ibrahimovic meanwhile got away with a yellow card and is probably already bracing himself for his next meeting with the 2006 World Cup winner.
Footage of Zlatan's kung-fu kick on Marco Materazzi is on the video below.
It should also be pointed out that Zlatan is of course a black belt in Taekwando (here he is meeting the Italian national team last week) and the crazy Swede doesn't just kick opponents, but team-mates as well as Robinho found out last week.
