Arsenal midfielder Thomas Partey asked the club's supporters to "join us in a celebration of United's loss" in bizarre viral video.
Partey made the cheeky dig while speaking to social media star Nana Aba, who boasts 3.3million followers on Instagram and 1.9m followers on Twitter. The video emerged after Manchester United suffered a 2-0 loss at Newcastle on Sunday afternoon.
In the clip, Nana Aba films Partey and says, "Arsenal fans, I am with your super-duper midfielder Thomas Partey." The Ghanaian, who started Arsenal's 4-1 win against Leeds on Saturday afternoon, then replies, "You're welcome, join us in celebration of United's loss."
