Amorim is still expected to fly into Manchester on Monday
Mikel Arteta was left praying on the fitness of his Arsenal players after his team slipped nine points behind Premier League leaders Liverpool.
With the last attack, William Saliba broke down the Arsenal left and crossed low. There was Kai Havertz in the middle. Centre of goal, six yards out, unmarked. He would have had a tap-in against his former club, Chelsea, and Arsenal would have had a precious last-gasp victory. The kind of statement win that propels teams back into title races.
