Paul Merson was left stunned by Kai Havertz's bizarre reaction after his handball saw Arsenal's late goal ruled out in their 2-2 draw with Aston Villa.
Mikel Arteta's side looked on course to close the gap on runaway Premier League leaders Liverpool after goals from Gabriel Martinelli and Havertz, but Villa hit back in a breathless second half through Youri Tielemans and Ollie Watkins.
The result leaves the Gunners six points adrift of top spot, although the deficit appeared to have been slashed when Merino's strike deflected in at the death.
