Ryan Giggs has claimed that facing Liverpool is a bigger match for Manchester United and a bigger test for any United player than taking on Premier League rivals City in the Manchester derby.

United and City are limping into the first showdown of the season, which takes place on Sunday, following midweek Champions League defeats, yet their dominance of the Premier League scene is such that the pair have already established a massive advantage over third-placed Chelsea, enough for many to render this season's title battle a two-horse race.

The pair's scrap for honours last season was only decided in virtually the last minute of the last game, when Sergio Aguero scored the goal that sent the Blues into ecstasy, but 39-year-old Giggs, who boasts a record 35 appearances in the fixture, refuses to lift City above any of the other fierce rivalries United have had down the years.

'It doesn't mean anything extra because it is City,' said Giggs. 'Liverpool has always been the biggest rival for me. It has always been the biggest test.

'There are different rivalries. Arsenal were a brilliant team and we had some ferocious battles with them. Chelsea were also a brilliant team under (Jose) Mourinho and now City are a good team as well.

'The added dynamic is that they are on our doorstep. But we still want to win the league no matter who we are competing against.'

It is well over two decades ago now that Giggs turned up for training at City's youth set-up wearing a United kit, eventually jumping at the chance to switch to the club he supported and has now made 920 appearances after captaining the Red Devils in their 1-0 Champions League defeat to CFR Cluj last night.

Until 2008, the thought City might actually deprive him of silverware was laughable.
Sheikh Mansour's deep pockets have changed all that though.

And whilst Giggs agrees with Sir Alex Ferguson's assessment that Chelsea cannot be written off, after losing out on goal difference to a side they failed to collect a single point off in their two meetings last term, the Welshman is aware how significant Sunday's game can be.

'We have found over the last couple of years that the derby, with the money City have spent and the quality they have brought in, has got bigger and bigger,' said Giggs.

'The two games against them were the difference last season. Hopefully we can get the right result and that will be the difference come the end of this season.'

It promises to be a fascinating occasion, not least because of the obvious flaws in their respective make-ups.

City remain unbeaten. Yet they crashed out of Europe altogether this week after the worst Champions League performance by an English club in the competition's history and have drawn three of their last six games in the Premier League.

United boast the league leadership, but in doing so have conceded 21 goals - more than relegation threatened Sunderland - and Sir Alex Ferguson said earlier this week if there was any repeat of the appalling defending on show at Reading last weekend 'God knows what will happen'.

'We are both in a similar situation,' said Giggs.

'We are in a good position in the league but haven't hit the form we did in parts last season.

'That can be frustrating because we want perfection.

'We want to be the best team and each individual wants to be the best player.

'We must be doing something right because we are in a good position and there is the belief we can score goals.

'But that doesn't mean we should neglect our defending and not try and stop the goals we are leaking because we need to stop conceding them.'

It is a point Ferguson has drilled home countless times this season already.

And it is one that is steering the United boss towards a feeling Sunday's game will be a sterile affair.

'On paper, it is a match between the two best teams in the country,' Ferguson told United Review.

'As the table tells us, there is not much between us.

'We need to come out unscathed and with so much at stake I wonder if there will be a little bit of caution from both clubs.

'Roberto Mancini and I will both have to think deeply about our selections and tactics and there may well be an element of playing safe.'
