Arsenal midfielder Tomas Rosicky credits their revival to a tactical change.

With tough ties against Manchester United and Chelsea to come before the campaign is out, Rosicky insists the Gunners will not let up their good form after winning seven straight league games.

He told arsenal.com: "It's nice to see that we won [against Liverpool] in a convincing manner.

"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."
