WEST HAM'S miserable run without a win continued as they crashed out of the Carling Cup at the hands of League I side Chesterfield at Saltergate.
Caleb Folan, who used to be a Town season-ticket holder on the Kilner Bank, threaded the ball through Robert Green's legs with three minutes remaining to extend the Premiership side's losing streak to eight.
Marlon Harewood had ended the Hammers' run of seven games without a goal when he lashed in a volley after four minutes.
The hosts levelled nine minutes into the second half when Green tipped Folan's shot onto the post and Colin Larkin steered in the rebound, then Folan sealed the 2-1 win late on.
Birmingham manager Steve Bruce took his side to former club Sheffield United and claimed a 4-2 victory at Bramall Lane.
Former Town boss Bruce watched as the hosts took the lead through a fine Ade Akinbiyi strike but the Championship promotion hopefuls were level after a fluke goal from Dudley Campbell before the break.
Nicklas Bendtner's cool finish with 20 minutes remaining put Blues ahead and Huddersfield-born Cameron Jerome made it 3-1. Nick Montgomery pulled one back but Sebastian Larsson sealed the win with Birmingham's fourth.
New Leeds boss Dennis Wise was at Elland Road as his side were defeated by Southend.
The hosts fell behind to a penalty from Steven Hammell and a strike from Gary Hooper.
Ian Moore pulled one back a minute before the break but Hooper restored Southend's two-goal lead and it remained 3-1.
Arsenal moved safely through to the last 16 of the competition after a Jeremie Aliadiere double against West Brom at The Hawthorns.
The French youngster's first came from the penalty spot after his own exciting run was ended by Steve Watson.
The second was set up by teenager Theo Walcott whose free-kick in the 49th minute was cut back for Aliadiere to finish.
Watford held on for a 2-1 victory against Hull at Vicarage Road.
Ashley Young's free-kick and a strike from Tamas Priskin had put the hosts in control, but Nick Barmby's bicycle kick made for an intense finale.
