12. Ali Dia
https://www.youtube.com/watch?v=PyI-OfT7zYM One of the most curious cases in Premier League history, Ali Dia made just one appearance for Southampton as a substitute (before being subbed himself) after convincing manager Graeme Souness of a completely fabricated background. Claiming to be the cousin of George Weah, Dia conned Souness into believing that he had 13 international caps and several appearances at Paris Saint-Germain to his name. None of this was true, and he was quickly shipped to non-league Gateshead where he made just eight further appearances.
