Coach Francesco Guidolin has taken no comfort from Udinese's display at Arsenal. "We still lost the game."
Despite an encouraging performance from the Italian side at the Emirates, Arsenal have taken a 1-0 first leg advantage in their Champions League qualifying tie.
"I've told the boys that they shouldn't feel satisfied," the tactician told Sky Sport Italia. "We did nothing important out there because we lost.
"1-0 is also a very dangerous result."
Arsenal took the lead early after Theo Walcott tapped in from close range following some good work by the Premiership side.
"We started the match timidly," continued the former Vicenza boss. "And unfortunately we were without Maurizio Domizzi in defence.
"He's an expert player, whereas Neuton has still got a lot to learn about being a defender. He'll have a bright future, but our future is now.
"Arsenal are a young side, yet experienced in this competition and they took home the win. We just were not able to complete our display with a goal."
Udinese will now have to beat Arsenal by two clear goals on 24 August if they are to reach the Champions League group stages.
"The tie is still open and there is all to play for," continued Guidolin. "They have the advantage though and if they score then it'll be tough to get through."
