There are only 11 Premier League teams left in the FA Cup as we head in to this weekend's fixtures, which reflects what an exciting third round we had.

Sometimes, the latter stages of the Cup can look like a Premier League fixture list, but we've had a few shocks this year and a few more top flight teams will fall by the wayside this weekend.

The story of the Cup so far is probably Havant and Waterlooville's remarkable progress. The Blue Square South side's reward is a trip to Anfield.

Liverpool have got a few problems at the moment, but if they don't win by five of six goals I'll be very surprised.

But that's not really the point - only the FA Cup could pit a group of amateurs against the seven-times winners at one of the most famous grounds in the world.

I'll be in the commentary box at Mansfield's Field Mill stadium for the visit of Middlesbrough in Match of the Day's first live game of the weekend on Saturday lunchtime.

Mansfield are one off the bottom of League Two and recently lost 4-0 at home to Wycombe, so it would be a major surprise if they won.

But the Stags are expecting their biggest crowd in a long time and with Middlesbrough struggling for goals, a shock could be on the cards.

The BBC cameras will also be live at Wigan for the visit of Chelsea on Saturday tea-time.

The 'wobble' Avram Grant's side were expected to suffer during the Africa Cup of Nations really materialised, and while I think this will be a tight game, you have to fancy the holders to progress.

Tottenham, on a massive high from their midweek thrashing of Arsenal, face Manchester United on Sunday live on BBC ONE.

It's over 18 years since Spurs prevailed at Old Trafford, but with cup expert Juande Ramos at the helm, I'm backing Tottenham to book their place in the fifth round.

Every fourth round goal will be available on the red button following Saturday's Match of Day highlights show.

Steve Wilson was speaking to Paul Atherton.
