Boothroyd said: “I am very pleased we are making chances and I’d be more upset if we weren’t creating those. But at this level, if you don’t take your opportunities you will be punished.
“We thought we could have upset Arsenal’s party but it I was still very proud of my team.
“A lot of teams come here and just lay down but we kept going and created a lot of openings. But against these sort of sides you have to take them.
“This is a whole new level for us and it’s only a matter of time before we get that first win.”
