Ferguson on Chelsea attack
Mourinho and Ferguson face each other in the Premiership opener
Manchester United boss Sir Alex Ferguson has reignited his feud with Jose Mourinho by claiming Chelsea's spending will not guarantee success.
Ferguson was involved in a furious row with Mourinho, when the Portuguese's former club Porto sent United crashing out of the Champions League in March.
And the pair will resume their rivalry on the opening weekend of the campaign when United head to Stamford Bridge.
"Money isn't the issue. Picking the right players is," said Sir Alex.
Chelsea have added Didier Drogba, Peter Cech and one-time United target Arjen Robben to their squad this summer.

But Ferguson does not believe Roman Abramovich's millions will automatically see them lift the title and claims United can make a big impact during the campaign.
"It could be a very interesting season because Chelsea have a new manager, as have Liverpool, while myself and Arsene Wenger are becoming the old fuddy-duddies of the league.
"I do see improvement in teams like Tottenham but essentially ourselves, Arsenal, Chelsea and Liverpool will be the ones challenging."
