Arsenal manager Mikel Arteta praised the impact of his substitutes after his side beat Nottingham Forest 1-0 in the seventh round of the English Premier League.
The result kept Arsenal in second place, but Arteta acknowledged that his team had struggled to create clear chances before the interval.
“We did not have a single shot on target in the first half,” Arteta said.
Arsenal will return to Premier League action on 24 October, when they face Everton. Three days earlier, they will travel to play Bayern in the Champions League.
