Tottenham boss Harry Redknapp admits Arsenal are returning to their best thanks to defensive injuries now clearing up.
Redknapp feels Spurs' north London rivals have turned a corner now they have key players like Thomas Vermaelen and Laurent Koscielny fit.
"Arsenal suffered when they lost one or two key players and now they are getting a couple back," the Spurs boss said.
"They are starting to play well now. It's about having your best players. You need your best players available if you are going to be consistent and pick up the right results."
