Leaders United remain wary of shock results

Ryan Giggs is taking nothing for granted even though Manchester United's grip on the Premier League appears to be strengthening.

United head to Birmingham tonight still unbeaten following Sunday's win over Sunderland and with daylight starting to appear between them and their nearest challengers.

A quirk of the fixture list means Sir Alex Ferguson's men might well have been overhauled by local rivals Manchester City when they kick off at St Andrew's.

Yet City would have played three games more for their single-point advantage, which leaves Ferguson with plenty of breathing space before that particular initiative is surrendered.

However, Giggs is not getting carried away.

The veteran Welshman is acutely aware that, in this of all seasons, shock results can crop up at any time.

"You are obviously wary because of the way the league has been this year," said Giggs.

"Anyone can beat anyone. We are thankful we remain unbeaten and confidence is high. But we realise that nothing can be taken for granted.

"It is a tough league and we need to be at our best in every game."
