Manchester United defender Rio Ferdinand says there's a new intensity from the players following the arrival of new manager David Moyes.

Ferdinand has already detected a fresh impetus to the Red Devils squad as a result of Moyes' presence.

"It's natural that everybody is trying to impress on this tour," Ferdinand told the club's official website.

"When you get a new manager, you want to show him that you should be in the starting XI for that first day of the new season. That process has started already."

"We've been back from our holidays for more than a week and it's been a really good start.

"It's been very hard but it's been enjoyable and we'll see the benefits of the work we've been putting in back in Manchester and the work we're about to do on tour in the shape of better fitness and a better understanding of the personalities of the players and coaching staff.

"It's a new era for all of us. Hopefully things will come together and we can get off to a good start once the season begins."
