Peter Reid. Failed a medical and was believed to be completely finished as a player when Howard Kendall signed him. Went on to be an integral part of a squad that won the FA cup, then league and Cup Winners Cup the following year and were runners up in the FA cup the same year. Then went on to finally win international caps, playing in a World Cup tournament in Mexico. Not bad for a veteran journeyman midfelder, who was finished a couple of years earlier.
