Scott Parker says West Ham United will travel to Manchester United with "massive confidence" following back-to-back wins over Birmingham City and Hull City.
The Hammers recorded consecutive Barclays Premier League victories for the first time since March 2009 by overcoming Hull 3-0 at the Boleyn Ground on Saturday.
Having picked up six crucial points to rise to 13th in the standings, Parker insists a visit to Old Trafford should hold no fear for Gianfranco Zola's side.
"I said a few weeks ago when we were on a bit of a bad run of results that, if we could put two wins back-to-back, we could really go places. We've now got those two wins back-to-back and hopefully we can push on.
"We've got a tough game at Manchester United on Tuesday but, if you look at our home games, they're winnable fixtures, so we've got to keep going if we can.
"We go there with massive confidence. We've had two good results against an in-form Birmingham and we came out worthy winners on Saturday, so we go there with confidence. We all know how hard it is going to Old Trafford, and they're coming off a little stinging at Everton [where the champions lost 3-1 on Saturday], but we'll go there and see what we can do."
West Ham's improved form has coincided with a boost to Zola's attacking options, with the return to fitness of Carlton Cole and Guille Franco, coupled with the arrivals of Mido, Benni McCarthy and Ilan late in the January transfer window.
Parker believes the wealth of forwards at the club, combined with a settled back-four and midfield, has been a telling factor in the recent upturn in results.
"I think, at the moment, everyone is either fit or coming back to fitness. We've got practically a full squad, with Luis Boa Morte and Kieron Dyer coming back. It's probably the first time this season that we've looked so strong.
"We obviously brought forwards in in January, which is helping massively, and Coley is back and Franco came back on Saturday, so everything is going in the right direction for us and we can really start putting some results together now."
While Cole has scored in those two victories over Birmingham and Hull, Parker said that the role of Franco in Saturday's win - and his potential influence at Old Trafford - should not be overlooked.
"He's a very clever player. He drops into those little spaces which are hard to mark. He's crucial for us, really."
