QUIZ: Name these players based only on three of their former teammates

We seriously hope you're ready for a challenge.

Occasionally in life you face a quiz which makes you question the very meaning of life itself, which makes you wonder why you even bother. This is not one of those quizzes, but it is quite difficult. Your mission, should you choose to accept it, is to figure out who these footballers are based purely on three of their former teammates. A little heads up - some of these people are current players, while some are retired. Some are obscure, some are very well-known, and all are pretty difficult. So best of luck, enjoy yourself and let us know how you got on.
