New keeper David de Gea will become the 10th player to represent United whose name ends with an 'A'.
Judging by our research, we believe there are NINE others who have played for the Reds in competitive games - and all of them during Sir Alex Ferguson's reign.
We're not counting Brazilian twins Rafael and Fabio who could be included if using their da Silva names as well. The answers are based on the names listed on the official Stretford End stats site.
Here's the answers as promised: Eric Cantona, Eric Djemba-Djemba, Patrice Evra, Federico Macheda, Giuliano Maoirana, John O'Shea, Paul Rachubka, Louis Saha and Antonio Valencia. Thanks for taking part - we'll have another puzzle next Friday!
