Håland is often remembered for his feud with Roy Keane. In September 1997, when Manchester United were losing 1-0 to Håland's Leeds United at Elland Road, Keane injured his anterior cruciate ligament. As Keane lay prone on the ground, Håland criticised Keane for an attempted foul and suggested that he was feigning injury to avoid punishment. Keane was booked as he was stretchered off the field. He was out of action for nearly a year afterwards, missing the remainder of the 1997-98 season.

Three and a half years later, in April 2001, Keane fouled Håland, high up on his right knee. Initially, Keane was simply fined £5,000 and received a three-match ban. However, in his biography he admitted that he wanted to "hurt" Håland as revenge for the criticism he received years previously. After this revelation, Keane found himself subject to an FA inquiry and received an additional five game ban, and £150,000 fine.

and keane's admission: I'd waited long enough. I fucking hit him hard. The ball was there (I think). Take that you cunt. And don't ever stand over me sneering about fake injuries.

and that's how my sport philosophy come about. u play sport, get ready to see dirty.

sport is something played by humans, not by saints. we humans love dirty tricks. we humans love to outright break the rules and the law.
