Yakubu came up against United again on Monday night and he's scored against the Reds for three different clubs in the Premier League.
The Blackburn attacker, who scored twice at Old Trafford on New Year's Eve, has also hit the net for Portsmouth and Middlesbrough against Sir Alex's side at league level as well as Maccabi Haifa in Europe.
We wanted to know, firstly, which player has netted against the Reds in the Premier League with FOUR different teams and also the five others who, like Yakubu, have achieved it for three clubs.
Please note that we are only including Premier League strikes so the likes of Steve Stone and Darren Ambrose, who have scored against United for three clubs but including in cup competitions, do not count. This is from our research based on the goalscorers credited in the official United Yearbook.
The answers are in the black box to the right. Look out for another poser next Thursday.
