Sir Alex Ferguson believes Manchester United come face to face with the biggest obstacle to their quest to reclaim domestic superiority this season when they take on Chelsea in Sunday's Community Shield.
Although Manchester City have once again been England's biggest spenders this summer, Ferguson is adamant last season's double winners are the team to beat.
Chelsea boss Carlo Ancelotti has been active in the transfer market, striking early to lure Yossi Benayoun south from Anfield and then agreeing an £18 million fee with Benfica for Brazilian midfielder Ramires.
And, although there are still doubts hanging over the futures of defensive duo Ashley Cole and Ricardo Carvalho, Ferguson will be looking to Stamford Bridge for the main danger this term.
"With the experience Chelsea have got, you have to look at them being the biggest threat," said Ferguson.
"They won the league and the cup last year and I do think you have to see the team that won the league as the ones you look at."
"I don't see why anyone should think any different. Chelsea have the experience. You can't dismiss them."
