Liverpool legends don't come tougher than the 'Anfield Iron'.

Widely recognised as one of the game's hardest-ever players, Tommy Smith's reputation goes before him – as anyone unfortunate enough to have been on the receiving end of one of his bone-crunching tackles would no doubt testify.

Bill Shankly once claimed that his centre-half 'wasn't born, he was quarried' but, contrary to the claims of his critics, Smith was not your archetypal clogger.

More than 600 first-team appearances for the Reds and a glittering array of winners' medals are ample proof of that fact.

As a defender who possessed determination, power and raw aggression in equal abundance, not to mention a lot more skill than he was given credit for, he was a key figure during Liverpool's reign of supremacy in the 1960s and '70s.

A former Anfield apprentice, he skippered the club to league and UEFA Cup glory in 1973 and famously headed home the second goal in Rome four years later.
