Neil McDonald believes it is only a matter of time before West Ham United replicate their barnstorming away form at the Boleyn Ground.
The assistant manager has watched the Hammers net nine goals in winning all three npower Championship matches they have contested on the road.
However, the same players have only managed to muster a draw from their opening two home fixtures, conceding late goals in losing 1-0 to Cardiff City and drawing 2-2 with Leeds United.
With Portsmouth to visit east London on Saturday, McDonald is confident that frustrating record is about to change - particularly given the quality of signings made by the club during the final days of the transfer window.
England midfielder David Bentley, Ivory Coast defender Guy Demel and MK Dons goal machine Sam Baldock are among 12 new faces to join the Hammers this summer, giving the No2 cause for optimism ahead of the Pompey showdown.
"You would like to think the squad is looking very strong now on paper," he told West Ham TV. "We have had David Bentley who has come in and trained this week which was a huge confidence-booster for everyone.
"I think the other players who we have brought in create a good atmosphere of competition. If you play well, you'll keep your place and if you don't someone is ready to come in and take over - that's all you want from a squad at this stage of the season.
"I think the manager has set out to have two players challenging for each position. The competition for places is now on. We got a fantastic win at Forest which now seems ages and ages ago, but we'll be ready for Portsmouth. If Sam keeps the same team, he keeps the same team, but if he changes it then the challenge is there for the players to stay there.
"I hope the record will go this weekend. The confidence is there away from home where we're scoring goals for fun.
"We just need that little bit of luck. In our two home league games, we've created lots and lots of chances but we've not been clinical enough, especially against Cardiff. We scored twice against Leeds which was fantastic, but we were bitten right at the end.
"We need to concentrate for 90 minutes, create lots of chances and be clinical which we have certainly been away from home. We need to do that at home now."
While Bentley is a known quantity to Allardyce, McDonald, his team-mates and West Ham supporters alike, the assistant manager is also excited about the impacts Baldock and Demel could have on the squad.
"Sam has trained with us for a few days and has looked very sharp in front of goal. He has fantastic movement, is quick over the ground and is a goal-scorer. I think that's evident from what he's done with MK Dons over the last couple of seasons.
"He has scored goals for fun so if he can get into the team and we have give him the service, that will be fantastic for us.
"Guy has come in with a good reputation. He can play all over the place - at right-back and centre-half. He looks fit and well and has played at a high level in Germany and is obviously an Ivory Coast international.
"He's a fantastic signing and it gives plenty of scope for the manager to change things around if he needs to."
