We all claim to know our clubs like the back of our own hand. We've supported them through thick and thin, enjoying the good times and persevering with the bad.
Fans will have seen hundreds of players come and go throughout the years as different managers tried to put their own stamp on the team.
We sometimes see more of them than we do our own families. Some have left a bigger mark than others. Some, quite frankly, are forgotten as soon as they're ushered out the door.
But could you recognise them from a still image. Test your knowledge and take our quiz, seeing how many you would get out of the 18 pictures on show.
Answers will be revealed on page 5. Jot down your answers and see how many you get.
We've made things a little easier for you in part one. Keep your eyes peeled for more quizzes coming soon.
