Arsenal were frustrated to a 0-0 draw by Nottingham Forest at the City Ground on Saturday after failing to break down a stubborn home defence.
The Gunners dominated possession and created chances, but Gabriel Martinelli missed from close range while Bukayo Saka was denied by a fine second-half save.
A late penalty appeal for handball against Ola Aina was checked by VAR and waved away.
Forest earned a valuable point in their relegation fight with a disciplined display.
Arsenal remain top of the Premier League but missed the chance to extend their lead, now sitting seven points clear after 22 matches.
