Manchester United defender Rio Ferdinand is delighted with their improved away form this season.

Ferdinand feels improved focus explains the upsurge in rewards.

"Last year, I don't know what it was," the defender told MUTV. "It could have been complacency, expecting to win games whereas at the moment we're being very professional.

"We're hard to break down, hard to beat and we know that we've got players on the break who can beat anybody. [White Hart Lane] is a tough place to come. Spurs are a team with talented players.

"We've had that over the years; we've never had an easy win here. We knew we had to work hard and they made us work hard for the win."
