Jack Collison wants West Ham United to replicate the performances they put in at Stoke City and at home to Chelsea when they travel to Stamford Bridge on Sunday.

The Hammers achieved two of their finest performances of the 2012/13 Barclays Premier League season in winning 1-0 at the Britannia Stadium a fortnight ago and 3-1 at home to the Blues back in December.

Collison, who scored the match-winner at Stoke, believes a similar display could pay dividends in west London.

"It was a really great team performance at Stoke and I think it came at the right time," said the No10. "We have struggled a little bit away from home this season so it was massive to get the three points and keep a clean sheet, which will have pleased the gaffer!

"It was a great little ball from Vaz and luckily I was able to tuck it away. After the goal, we dug in really well and I thought the back four and Jussi Jaaskelainen did well to keep a clean sheet.

"We knew what to expect. The manager had prepped us all week so we knew what we were going into and I believe we were only the second team to win there this season, so that gives us a good bit of confidence going into the game on Sunday."

West Ham start the weekend as one of five teams on 33 points in the table, nine clear of the relegation zone. While the Hammers are not yet safe, Collison says the squad know they could finish in the top ten if they finish the season strongly.

"It's a little bit of a funny position. There are teams below us who can catch us, but there are teams above us who we can catch and go past. We're just taking it game-by-game. We've got our targets and if we achieve them we'll be in a good position at the end of the season.

"I think we've got to push on, especially after a good result in our last game. We've had a little bit of a break since then and we've done some good training so, come Sunday, we'll be ready and raring to go.

"I think it's given a chance to get some good work under our belts and some good fitness work done and it's given the manager a chance to work on his team shape and get a few of the injuries a bit closer to making a return."

Concentrating on Sunday's trip to face Chelsea, Collison is eyeing a repeat of West Ham's outstanding display against the Blues in December. The Wales international missed that game as he managed his long-term knee condition and is determined to play his part in achieving the Hammers' first league 'double' of the season.

"Chelsea are obviously a team full of world-class players from the goalkeeper to the strikers so we know it's going to be a tough game, but I thought our lads were magnificent in the game against them at Upton Park. We got a great result that day and it gives us confidence going into Sunday.

"It was a great game. I was watching as a spectator myself unfortunately, but it was a fantastic game and Mo Diame has probably put in one of the performances of the season there. He came on and was magnificent. The boys dug in and got a great result.

"I think it would be great for confidence to finish well and as high up as we can. The manager wants us to push on and get safe and that's what we want to do as a team as well."
