Chelsea v Manchester United: Chelsea will be main challengers in pursuit of title, says Ferguson

Although Manchester City have once again been England's biggest spenders this summer, Liverpool have kept hold of Fernando Torres and Steven Gerrard and Tottenham are buoyed by a favourable Champions League qualifying draw, 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 18m 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."

Not that Ferguson is ignoring the other challengers either.

He has been saying for years now that the general standard at the top end of the table is improving and is convinced the trend is continuing, despite Sam Allardyce's claim that more top players are being put off Premier League life by the 50 per cent top rate of tax.

"It is a league with a lot of dangers," he said. "The competition is being raised all the time.

"Last year, the monopoly of the big four was squashed when Tottenham came into it and they will make progress this year.

"Manchester City have bought again, so you obviously have to put them into the equation and Everton, who had so many injury problems last year, will also come into it.

"There is no doubt in my mind it is going to be a more competitive league every year now."

Ferguson will be without United midfielder Michael Carrick, who will miss the start of the season after injuring his ankle in Wednesday's friendly in Dublin.

Ferguson has confirmed Michael Owen and Wayne Rooney will both feature for 45 minutes tomorrow.

Brazilian twins Rafael and Fabio are doubtful after suffering food poisoning during the week.

Hilario will start in goal for Chelsea.with striker Didier Drogba will be on the bench, while No 1 Petr Cech, defender Alex (both calf) and full-back Jose Boswinga (knee) are all out.
