The League Cup fourth round nearly produced a shock with Birmingham City requiring a late, late equaliser to force their game against Brentford into extra-time where they would eventually triumph over their League One opponents by way of a penalty shoot-out.
Sam Wood's accurate finish put the visitors in the lead on the 67th minute and the Blues looked to be heading out of the competition only for Kevin Phillips to pop up with a late and dramatic equaliser with 90 minutes on the clock.
So into extra-time the game went, but neither side could quite find the breakthrough from open play during the added 30 minutes, with Craig Gardner coming close for the Blues.
There was only one way this was going to be settled and from the ensuing penalty shoot-out, it was Alex McLeish's side who held their nerve to squeeze through 4-3 from the spot.
Birmingham: Taylor; Carr, Dann, Ridgewell, Parnaby; Bowyer, Gardner, Michel, Derbyshire; Phillips, O'Connor.
Brentford: Lee; Spillane, Legge, Osborne, Woodman; Wood, Bean, O'Connor, Weston; Alexander, MacDonald.
Leicester City 1-4 West Bromwich Albion
Leicester's new manager Sven Goran-Eriksson witnessed his Championship outfit suffer a crushing 4-1 defeat to high-flying West Bromwich Albion inside the Walkers Stadium.
Simon Cox opened the scoring with a neat finish from inside the box on the 20th minute to ensure the in-form Baggies took a lead into the break.
City were back in the match early in the second period after Nicky Shorey put through his own net but within 10 minutes of the own-goal Roberto Di Matteo's side restored their lead after a neat Somon Tchoyi strike. Then further goals from Steven Reid and a late second for Cox sealed an emphatic result for the away side.
Leicester: Logan; Neilson, Morrison, Miguel Vitor, Berner; Abe, King, Dyer, Gallagher; Howard, Moussa.
West Brom: Myhill; Pablo, Cech, Meite, Zuiverloon; Reid, Tchoyi, Dorrans, Barnes; Cox, Bednar.
Wigan Athletic 2-0 Swansea
Elsewhere, spectators inside the DW Stadium had to wait until the second half to witness the Latics go ahead through a close range Mauro Boselli strike.
From then on it was squeaky bum time for the Premier League side for half an hour until Roberto Martinez's side were awarded a late penalty and settled their nerves through Ben Watson's conversion from the spot.
Wigan: Al Habsi; Stam, Gary Caldwell, Alcaraz, Figueroa; Moses, Watson, Thomas, Diame, Gomez; Boselli.
Swansea: Ma-Kalambay; Rangel, Tate, Serran, Taylor; Cotterill, Pratley, Agustien, Van der Gun; Emnes, Beattie.
