Jozy Altidore's Sunderland shocker continued as his first-half miss consigned the Black Cats to their fifth draw in their last six matches
West Ham live updates
Stewart Downing insists West Ham are loving upsetting the odds after they gatecrashed the top four.
The Hammers are fourth in the Barclays Premier League ahead of Saturday's trip to Sunderland.
Boss Sam Allardyce spent a reported £31million in the summer which was been dwarfed by the expenditure of Manchester United, Arsenal and Liverpool.
– England and West Ham midfielder Stewart Downing
It's good, teams have spent a lot of money and people expected them to be in the top four because of what they've spent but it doesn't always work that way. We have bought very well, the players coming in have settled well. Sometimes you see players coming to the Premier League struggle to adapt. It's a big plus for us.
If you looked at the league at the minute you'd say it was false but we're there on merit, we've done well and we've played some big teams and played them off the park on the day.
We've beaten Liverpool and Manchester City and ground out a win against Newcastle, which we would have lost last season. We have shown good qualities.
Swansea have announced they will be appealing the red card shown to goalkeeper Lukasz Fabianski during Sunday's Barclays Premier League defeat to West Ham.
The Poland international was dismissed in the 68th minute of the match at Upton Park for impeding West Ham substitute Diafra Sakho as he burst through on goal.
However, Swansea manager Garry Monk said after the 3-1 loss that he expected the club to appeal the decision, saying there was both a handball by Sakho in the build-up and that it was not a clear goalscoring opportunity either, and on Monday the Welsh club confirmed they had been in touch with the FA.
– Swansea City statement
Swansea City can confirm that the club will be appealing the red card issued to goalkeeper Lukasz Fabianski against West Ham on Sunday. The club officially informed the Football Association by today's 1pm deadline.
The Polish international, who faces a one-match ban, was shown a straight red card by referee Chris Foy for impeding Diafra Sakho and denying a clear goalscoring opportunity in the 68th minute of the defeat at the Boleyn Ground. The FA will make a decision on the appeal ahead of Sunday's Barclays Premier League clash with Spurs at the Liberty Stadium.
Sam Allardyce is hoping to have a trio of players fit and ready to feature in West Ham's Premier League clash with Swansea on Sunday.
The game may yet come too early for midfielder Mark Noble (calf) but Allardyce believes both Diafra Sakho (back) and Alex Song (knee) could play some part against the Swans.
With Enner Valencia making his own comeback from injury in the midweek victory at West Brom and Andy Carroll fit, Allardyce will now have all of his attacking options available as he looks to guide the Hammers to an eighth league win of the campaign.
Provisional squad: Adrian, Jaaskelainen, Cresswell, O'Brien, Reid, Tomkins, Collins, Jenkinson, Noble, Kouyate, Song, Nolan, Amalfitano, Downing, Jarvis, Vaz Te, Cole, Zarate, Sakho, Valencia.
