- Matti had unlimited self-confidence already as a young man.
His style of play was such that he could feint away the same back up to five times before putting the puck in goal.
Sometimes he did not even want to score goals but just entertain the audience, says former teammate Veli-Pekka Ketola, to Iltalehti.
Keinonen made 196 international appearances for Finland and participated in nine World Cups and two Olympics.
He accounted for a total of 120 points in the national team jersey.
In the 1965 World Cup, he was nicknamed the "Sweden killer" after scoring both goals in a 2-2 match, during a time when Finland was well behind Tre Kronor.
Keinonen was inducted into the 2002 Hockey Hall of Fame.
He turned 80 years old.
