Our latest teaser concerned the reign of Sir Alex only.
We were looking for players whose surnames begin and end with the same letter who have played for the boss in the first-team at United.
By our reckoning, there's six and none of them is a single letter name such as Anderson, Nani etc.
Well done to Cesta who appeared to be first to name the lot on the Talking Reds forum.
The answers are Sylvan Ebanks-Blake, Jonathan Greening, Tomasz Kuszczak, Alex Notman, Ryan Shawcross and Paul Scholes.
Look out for another puzzle next Friday.
