Arsene Wenger said Olivier Giroud is lacking confidence after the Arsenal striker stretched his run to 14 Premier League matches without scoring a goal.
Giroud's scored his last goal in the Gunners' 3-3 draw against Liverpool back in January, and was unable to stop the drought in their goalless draw against Sunderland at The Stadium of Light.
"It's true. The team got less forward to him in the second half. But strikers live on confidence and at the moment we have to be behind him," Wenger told Sky Sports.
"Our first half was good, the basis is good. The final ball was maybe not quick enough sometimes and our finishing was not the best.
"We had good domination but we created chances and didn't take them. It was the kind of game where we needed to go in front because I thought we might suffer physically.
"It's not the result we want, we wanted to win. It's not good but we focus on the next one, that's all you can do."
Arsenal missed out on the chance to climb from fourth to third in the Premier League table after their 0-0 draw with Sunderland on Sunday.
