Renica was the sweeper in Maradona's Napoli, in the early years he played also as left back. He had excellent left foot, famous for his fantastic long passes from defence and his rocket shot. He was also excellent in aerial play, and gifted technically. Pretty strong player, tough and sometimes too violent in tackling which caused a lot of penalties. He had good speed but wasn't particularly agile, looking clumsy sometimes. But he could start excellent solo runs from defence dribbling past couple of rivals, than sending good long ball on the wing or concluding the attack himself with rocket shot. He scored many goals with the head and from long range shots, even from free kicks. Anyway his offensive attitude left lot of holes behind him, which he couldn't cover it anymore when returning from the attack, and often those mentioned errors ocurred when he was late in tackle and caused the peanalty. Still he was one of the best sweepers in Italy, right behind Baresi who closed his chances of playing in NT.
