Sam Allardyce believes his West Ham United side have every chance of inflicting Middlesbrough's first home npower Championship defeat of the season on Tuesday.
The Hammers travelled to the North East on Monday afternoon ahead of a fixture that, should they win, could see them go top of the table.
Big Sam revealed to West Ham TV that, despite the absence of the injured Sam Baldock and John Carew, he and his squad are full of confidence as they look to make it six league games unbeaten.
"I think our form at the moment tells us that we have a lot of confidence," said the manager, who revealed Baldock had undergone a scan on his.injured hamstring on Monday.
"The only couple of small issues we have at the moment is the recovery of players and I think that is a big question for myself - who to risk, when to risk them and whether it be from the bench or from the start.
"Unfortunately we picked up the injury to Sam [against Derby County on Saturday] and an injury to John in training on Sunday, sadly. That limits our numbers a little bit. We've only travelled with 17 including young Dan Potts, so you can see how short of numbers we are again.
"We're generally full of confidence because our away form has been brilliant, but we face a very tough game against Middlesbrough. Saying that, they have conceded a lot of winning positions where they have drawn.
"Their problem is far too many draws at home, which tells us that they're not quite as good at home as people think they are. While they have played very well, they have left a few gaps for the opposition to capitalise on.
"On Saturday, they went ahead twice against Blackpool but allowed them to pull it back to 2-2. From our point of view, we know we've got a real good chance if we play to our best, which is what you always have to do when you play away from home - especially at Middlesbrough."
Looking back to Saturday's victory over the Rams, Allardyce pointed out that suggestions of West Ham struggling for form and results at home were well wide of the mark.
The Hammers have the fourth-best home record in the npower Championship, having won five and drawn two of their nine league matches at the Boleyn Ground.
"I think people are suggesting that all the time - particularly the media lads - because our away form is better than our home form.
"After the early season slip-ups when we were all getting to know each other - I was getting to know the players and we weren't so sure about ourselves and one or two of results suffered - and we're over that now.
"We're in our best spell of form in the last six games and we want to continue that on Tuesday and, at least, be undefeated when we come off the field."
