6) Luc Nilis (Aston Villa)
Only four minutes into a match with Ipswich Town a horrible collision between the Belgian and Ipswich goalkeeper Richard Wright brought the game to a complete stop. Nilis’ right leg bent backwards just below the knee, curling straight back up towards the ankle. He was hit with a double fracture and was forced to retire just four months later. Within four days of the match, he had already gone under the knife twice, and never recovered.
