Arsenal goalkeeper Wojciech Szczesny says after victory over Udinese they go to Manchester United on Sunday with confidence.
Szczesny is convinced Arsenal can use last night's victory as inspiration against champions Manchester United at Old Trafford on Sunday.
"The last couple of games before last night we had disappointing results but there was never a doubt in our heads that we are a very good side," he said.
"So we are going to put in a good performance on Sunday and see how it goes from there. The team believes we are capable of playing very well and winning games. It'll be tough for the rest of the season but I believe we have what it takes to come out on top."
The 21-year-old revealed he played mind games with Antonio di Natale as the veteran prepared to take his penalty.
He said: "I just tried to get in Di Natale's head. I gave him a little bit of stick and was probably not very nice to him but it worked so I'm delighted."
