Penalty pain for West Ham
Sheffield United claimed a Premier League scalp as they prevailed 5-4 in a Capital One Cup second round penalty shoot-out with West Ham United.
The Upton Park contest had ended 1-1 after 120 minutes, with Diafra Sako edging the hosts in front, only to see Winston Reid put through his own net to restore parity.
West Ham fans taunted their Sheffield United counterparts with chants about Carlos Tevez - only to see their latest big-money signing miss the decisive penalty.
This was the first meeting between the two sides since the Blades were relegated in 2007, largely thanks to Tevez's goals at West Ham - only for a legal wrangle over the Argentina international's ownership leading to the Hammers paying out almost £30million in compensation.
There are now two divisions separating the clubs but it is Sheffield United who progress into the third round after Enner Valencia, a £14million signing from Pachuca, was the only player to miss his spot-kick.
Stewart Downing lauded the depth of the squad now at Sam Allardyce's disposal in the build-up to the game but, with the West Ham boss making nine changes, his side struggled to show the class to see off spirited third tier opponents.
Sakho was quiet but managed to put the Premier League side ahead with a well-taken first-half header, only for Reid - captain for the evening - to score an unfortunate second-half own goal, with few chances created by either side as the game meandered into extra time and eventually to penalties.
Both sides converted their opening four spot-kicks before Valencia, who had wasted a couple of good chances during the night, saw his low effort saved by the impressive Mark Howard.
Blades' skipper Michael Doyle then stepped up to seal the win for Nigel Clough's side - who will see the result as a small piece of revenge for the whole Tevez saga.
