The midfielder has stated that the Gunners have made adjustments to their preparations before facing top teams.
A 2-0 win against Manchester City away from home and the recent 4-1 demolition of Liverpool on home soil are examples of the Gunners being able to compete with the best.
Long-serving midfielder Tomas Rosicky has revealed that the club have made a conscious effort to alter their approach to big games.
The Czech Republic international stated that this change in mentality will serve the North London club well in their remaining seven Premier League games this season.
“It’s nice to see that we won [against Liverpool] in a convincing manner,” Rosicky told the official Arsenal site.
“We know we can beat the big teams so that was nothing new - we wanted to win and the performance was good as well.
“We changed some stuff slightly in our preparation for these games. We’re doing a little more tactical work and we changed some stuff against the big teams.
“I don’t want to go into the details but there were some adjustments and it’s paid off for us. Recently we’ve been successful against the big teams but we still have to play Chelsea and Manchester United, so we would like to carry on like that.
“You can see the confidence is coming out of the players after a good run like we are on at the moment. You can see it on the pitch when you watch us play. We are not finished with this run, we will continue it so we have to continue working and working hard every day in training.”
Arsenal are seven points adrift of league leaders Chelsea in the race for the Premier League title, but have a chance to cut this deficit when they face their London rivals at the Emirates Stadium later this month.
Champions League qualification looks all-but secured for the Gunners, with an outside chance that the Blues may slip up and allow Arsene Wenger’s men back into title contention.
Rosicky has played a bit-part role in the campaign and suffered from debilitating injuries, starting only five Premier League games so far this season.
