Renquin was a tough but technical left back who, along with Eric Gerets, formed the best pair of wing backs in many years at the national team. He had enough quality to start dribbling, even when playing out from the back. No one could match him for that position in his best years. He often stood out in a strong Belgian team. He played in the World Cup twice (1982 and 1986) and in two European Championships (1980 and 1984).
