The Hammers were desperately unlucky to be held to a 1-1 draw by Manchester United in the FA Cup on Sunday after more magic from their hero Dimitri Payet.
His sumptuous late free-kick looked to have given Slaven Bilic's men a deserved place in the semi-finals at Wembley.
But Anthony Martial bundled home a scrappy equaliser to set up a fitting last ever FA Cup game at West Ham's Boleyn Ground home of 112 years ahead of their big move to the Olympic Stadium this summer.
The Hammers were left feeling hard done by after replays showed Payet should have won a penalty and there was a foul on goalkeeper Darren Randolph for the equaliser.
'Nobody scores all the time'
The 9,000 or more Hammers fans making their way home from Manchester were reeling but West Ham chief Sullivan told the club's official website that says everything about Slaven Bilic's East London revolution.
"It shows how far we have come to feel let down by a late goal and only a draw at Old Trafford," Sullivan told whufc.com.
"Maybe we should have scored more with the chances we had, but nobody scores all the time."
The Bilic revolution
Sullivan makes a salient point about the hopes and expectations at West Ham now which are a world away from the negative mindset towards the end of Sam Allardyce's tenure.
The most satisfying thing for Irons supporters is the fact West Ham are not just nicking the results with set pieces or a bit of luck here and there.
Bilic's freeflowing and resolute side are tough to beat and are not only holding their own but dictating these big matches.
