Puis was famous for his golden left foot which was at the source of many goals. He was the last of the pure ‘wing players’. With little steps, he dribbled the entire left side to give a strong cross. He formed the left side with Anderlecht teammate Paul Van Himst at the Red Devils.
He scored nine times for the Devils, played at the 1970 World Cup and the European Championship in 1972. He passed away on 21 October 1981 at the young age of 38 of cancer.
