Adam, currently on loan at Gillingham, but not allowed to play at Upton Park this weekend, says:
"Patrick Agyemang is always a threat and in midfield Danny Spiller looks sharp and is always likely to get a goal.
"That is two players with quality and attacking heads on them and they both they like to run at people and get shots off.
"I think Agyemang is the main threat because of his pace and ability on the ball, but it is nothing West Ham haven't dealt with before so I think we go into the game with confidence having beaten Stoke - and I don't think they will see it as a problem.
The Gills are on a long run of defeats, of course, and in the latest, Adam scored at Millwall midweek in a 2-1 reverse.
"I wasn't the most popular player on the pitch with the West Ham connection and it was nice to get the goal but the result soured it," he says.
"Gillingham have been getting better in every game and were definitely the better team before Millwall scored - but it was a cased of two sloppy errors in the first half that cost the team.
"In the second half Gillingham got the early goal and made loads of chances but just weren't able to put it in the back of the net.
"To come away from nothing from that game was a massive disappointed and Gillingham are desperate for a result now.
"They are looking forward to the game; it is going to be difficult for them to get something at Upton Park although they will go there with as much optimism as possible.
"But Gillingham are going in there with a bit more than they have done in a few weeks because the performances have gradually been getting better and better, and it will be an interesting game."
The Gills lie second from bottom with five points but Adam says:
"They are not playing like a team down there but the table never lies and it is results that count - maybe it is bad luck here and there.
"What it comes down to is errors that shouldn't happen at this level, little things like organisation, picking up the right men; there are just a lot of communication problems but it is definitely coming together.
"The attacking side of things was far better against Millwall with chance after chance created.
"As soon as they get one result I think things will turn round for them and I can't see them being down there for too long.
"The manager has changed his team a couple of times and so different personnel have been playing but there is some quality."
Adam's loan spell ends on Tuesday and Alan Pardew says:
"I am going to call him back because I will need him for Chelsea but it is possible for him to go back there - we will have to review that after the Chelsea game.
"It was always the aim to get him some games and he has played very well."
