A couple of months ago, The Echo asked Sunderland supporters to name the hardest players to have played for the club and with the World Cup now upon us, we take a look at what fans had to say.
Have we missed anyone from our list? Get in touch on Twitter and Facebook:

10. Billy Whitehurst
Whitehurst's, shall we say, robust style of play means he is considered by many fans to have been the hardest player ever to have played the game of football. Photo: Ben Radford
11. Mick Harford
Not to be messed with under any circumstances! Photo: Mark Thompson
