The shot-stopper believes that a victory at Old Trafford would be the ideal way to follow their Premier League triumph over Liverpool and Wednesday's victor in DortmundArsenal goalkeeper Wojciech Szczesny aims to ensure "a perfect week" for his side by beating Manchester United on Sunday.
The Poland international believes there has never been a better time for Arsene Wenger's side to visit Old Trafford, with the Premier League leaders in outstanding form.
The Gunners beat Liverpool 2-0 on Saturday before winning 1-0 at Borussia Dortmund in the Champions League on Wednesday and Szczesny wants to cap it off by extending their advantage over David Moyes's men to 11 points.
"We are looking forward to Sunday now and we will be trying to make it a perfect week for us," the keeper told reporters.
"We have got two clean sheets and two results against quality opposition, one away from home at one of the toughest venues in Europe.
"It would be amazing to get nine points from these three games, when probably not a lot of people expected us to do.
"There is not a better time for us to go to Old Trafford. We are very confident and enjoying our football, so we are looking forward to it."
Arsenal head into Sunday's match on the back of a 15-match unbeaten streak on the road in competitive fixtures, with 14 of those ending in wins.
