The FA Cup final this weekend sees the two Manchester clubs take each other one for another trophy and with the rivalry never having been so strong and we have done a fun horse racing based quiz linking to this weekends Derby game at Wembley.
The rivalry between both clubs and sets of supporters goes way back and with Manchester so passionate about football, there will be some huge bragging rights available.
In the racing world there are many horses that have been named after Manchester United and Manchester City players with other links from both clubs to horse racing.
We have asked you in the majority of these questions whether you can guess or you actually know the name of these horses compared to what players they are named after.
Sir Alex Ferguson was most well known in sport for being the greatest manager of Man Utd of all time but he was also a very keen horse racing owner and owned some very special horses during his career.
We've given you three minutes to correctly guess as many of these answers as possible and we're expecting some pretty good scores, so anything around the 8/11 mark is very good.
Good Luck and Tweet your scores into @TWEnclosure and the best scores will be retweeted.
