Manchester United defender Rio Ferdinand has warned England fans not to get carried away with the superb start to their World Cup qualifying campaign.

Ferdinand warned: "We've not qualified yet, so we're still learning from the manager; we're still in the campaign and we've had four very good results and we want to keep going in that right direction.

"There's no point if we stop now and only just scrape through, because people will say we're back to square one. It's about qualifying and continuing that."
