Arsenal's title bid received two potentially fatal blows over the weekend, which ended with Liverpool 11 points clear at the top of the table.
The Gunners lost 1-0 at home to West Ham United on Saturday, before Liverpool won 2-0 at Manchester City on Super Sunday.
An attacking injury crisis saw Gabriel Jesus, Kai Havertz, Bukayo Saka and Gabriel Martinelli all miss Saturday's game at the Emirates Stadium.
In their absence, Gunners boss Mikel Arteta started midfielder Mikel Merino as a makeshift centre forward, with Leandro Trossard and 17-year-old Ethan Nwaneri either side of him.
