Arsenal hero Martin Keown feels they missed an opportunity after their 0-0 draw against Europa League opponents Benfica.
The Gunners came from behind to draw the first leg of their Europa League last 32 first-leg and the tie remains in the balance ahead of the return fixture on February 25.
Keown thinks Mikel Arteta's side are short on confidence but is disappointed the Gunners could not take more from the game.
Keown told BT Sport: "I thought they (Benfica) were quite ordinary and that's why I'm disappointed – Arsenal didn't take advantage.
"When you get an opportunity to win, it didn't quite click and I understand why, playing the same XI from last week, but the team is short of confidence.
"If those goal flew in, you would've seen an upbeat Arsenal. I see an Arsenal team that's changed formation and a lot of problems for Arsenal is finding that spare player.
"Martin Odegaard hasn't played many games for Real but there were moments that he did well for the goal and they want to build around him."
