Which Man United and Arsenal players are mentioned most on Twitter? We've created a combined XI from their most popular players...
The two teams clash at Old Trafford on Saturday live on Sky Sports 1 HD from 11.30am and we've built a combined XI, based on global Twitter mentions this season.
United hold a slender lead over their London rivals for Twitter support, having 9.3m followers compared to the Gunners' 8.5m.
In terms of the players' popularity, the combined Twitter team is a Man United whitewash, with eight Old Trafford stars making the starting XI.
United 'keeper David de Gea (6.49m followers) gets the nod for Twitter popularity, ahead of Arsenal's Petr Cech (1.64m).
Old Trafford team-mates Luke Shaw (1.36m) and Eric Bailly (245k) line up either side of Gunners' new signing Shkodran Mustafi (214k) in a three-man defence.
It's a solid, three-man United midfield in Ander Herrera (1.6m), Wayne Rooney (14m) and Paul Pogba (2.93m), with all three able to sit deep or roam into attack.
Alexis Sanchez (1.83m) has been in blistering form as a centre forward for Arsenal this season, but could interchange with United's Marcus Rashford (354k) down the left wing.
Zlatan Ibrahimovic (4.26m) partners the Chile star up front, with Arsenal's in-form midfielder Mesut Ozil (13.7m) occupying the right flank.
