Mikel Arteta says football must “eradicate” social media abuse from the game in wake of Kai Havertz’s wife being targeted after Arsenal’s defeat to Manchester United.

Arsenal crashed out of the FA Cup third round on Sunday, with Havertz missing two great chances in the game and his penalty in the shootout.
