6. Ledley King
Ledley King was undoubtedly one of the best defenders that the world had ever seen, and was the best in Premier League arguably! He was so good that had it not been the string of injuries he would face, he could have become a first-team player every time for England and maybe players like Terry and Ferdinand might not even land a chance to play regularly for the country. He was so plagued with injuries that he ultimately had to call off his career because he wouldn’t be able to attend a single practice session with Tottenham.
