The Arsenal midfielder has been sidelined since Boxing Day with an ankle injury and broke down during his first serious session on January 27, suffering a recurrence of the problem.
He told the London Evening Standard: "It was definitely a big blow to get injured. I have had a couple of setbacks since but I am itching to get back out there and try and achieve something special this season.
"We put ourselves in a great opportunity early on and hopefully we can see it through now.
"I'm not back in full training yet - I'm outside with the fitness coaches. Hopefully, I will be back in time for the Tottenham game - that's my target but we will just have to wait and see."
