The Uruguayan's arrival provides the inspiration for our latest trivia question which is based solely on the Sir Alex Ferguson era at Old Trafford.
This week's trivia question was:
Can you name 12 players who were selected for the first team by Sir Alex whose surnames ended with the letter A.
Please note we are not counting Rafael and Fabio (Da Silva) nor any players who only traditionally use a single name.
Check out the answers in the black box - hopefully we haven't missed anybody out!
