It's FA Cup fourth round time and there's a dozen ties down for decision.
It's hard to know how many full strength teams will be fielded but there's definitely a shock on the cards at St Andrews where Birmingham City take on Swansea City.
Brum will give everything while Swans have been less than graceful of late and may start with some reserves on the pitch.
There's another Premier League banana skin on the cards at the DW Stadium with Wigan Athletic up against Crystal Palace.
The Cup holders are keen not to go out of the competition too early on and will cause Palace hearts to flutter.
Two top flight teams who shouldn't have too many problems are Liverpool at Bournemouth in the early kick off and Manchester City at home to Watford.
Ole Gunnar Solskjaer's only win with Cardiff came in the last round of the Cup and they should prove too strong for a struggling Bolton Wanderers at the Reebok.
Huge gulfs in class appear at the Stadium of Light where Sunderland take on the non leaguers Kidderminster Harriers and at League One Stevenage Borough where Everton are the visitors.
Elsewhere Yeovil make the trip to Southampton - Hull City travel to Southend - Port Vale are at home to Brighton - it's Rochdale against Sheffield Wednesday and Huddersfield receive Charlton.
