Manchester United boss Sir Alex Ferguson has no doubt there is money available for big signings this summer.

The Mail on Sunday says Ferguson is confident the Glazer family will back him this summer if he wants to sign a world star, such as Atletico Madrid's Radamel Falcao.

Incoming Old Trafford chief executive Ed Woodward was cautious about United's spending plans this week, despite the club's latest financial results showing quarterly revenues rising to £91million.

But Ferguson, who signed Robin van Persie from Arsenal last year to inspire a record 20th title for United, is confident he would be backed by the club's hierarchy again if he felt there was a player who could improve the club's chances of success in the Champions League.
