Marlon signed from Nottingham Forest just in time to play at Wimbledon on Tuesday night, forcing the best save of the match out of former West Ham keeper Stephen Banks, and he says:
"I feel wonderful to have played my first game and to be part of West Ham; it is a great opportunity for me to join a great club like this and I feel good.
"It was very hard against Wimbledon, having just signed, but the lads made me feel welcome and I was doing well - but we just lost it at the end.
"It was a pleasant surprise to hear about the move and when the gaffer told me about what his goals were with the club it took me straight away - and I am pleased to be at a big club like West Ham.
"It is definitely nice to be wanted at West Ham and what he wants to achieve at this club is fantastic.
"I know the lads from watching TV and the lads made me welcome, coming to shake my hand, talking me through the game, and it is just a shame we didn't win.
"I am definitely pleased to have got the move out of the way to come to a big club like West Ham so I can show my stuff."
West Ham now have six strikers but the competition doesn't faze Marlon, who says:
"Everyone should thrive on it; when you go out there you should want to keep your shirt and it is fantastic for the club."
And his impressions after a whirlwind 24 hours and a debut in Milton Keynes?
"I can't say what is going wrong after one game and in fact I don't think anything is going wrong; being in the dressing room with the lads - who are great - makes me think it is all going to come together in the next couple of games."
Next up is the home debut against Wigan after the luxury of a few training sessions with his new team mates; like Hayden Mullins, his initial signing was rushed through on a loan before he had even trained with the club with a permanent transfer being sealed the day after.
"I am looking forward to going out there and showing my stuff; with the awesome bunch of lads here I don't think it will take me long to fit in, and there is definitely better to come," he says.
Alan Pardew adds:
"It was a tough game for him against Wimbledon, but we were so short of bodies I felt it was a gamble worth taking; he showed some moments, I am excited by his capture, and I think it is a good deal financially for us.
"It is another guy who is out of contract at the end of the year so we have nicked two very good guys, in my opinion, for the future - but the immediate future is what we have got to sort out.
"But with him, Mellor, Deano, Defoe, Connolly, Garcia we have got a decent lot of strikers."
As Trevor Brooking said here, the option is to go with three strikers and Marlon enhances that possibility.
"I keep going to first division games and seeing teams being quite conservative and I think we are going to have a go at teams when we play three strikers," says Alan.
And Marlon agrees:
"It is an option; we have a few strikers here and there is good competition."
Cynics suggest that the signing of Marlon will lead to the sale in the new year of Jermain Defoe but Alan counters:
"I think the speculation around that was always going to be the case but that is not true; Marlon has been brought in because I wanted to add something down our right side and I thought he did that at times on the night even though there was not much room for him on the pitch.
"It is quite mouth-watering thinking of him, Connolly and Defoe in the same team - and there is big Deano, Neil Mellor, and Richard Garcia backing that up, so I am excited by that.
"And I am assured that I don't need to sell him in the window - so I am hoping now to have the firepower to take us up.
"But if we are going to start giving away sloppy goals it makes it all very difficult; a win would have been just what we needed and it didn't happen.
"I can only be reassured by the board and can only go by what I have found; I bought Marlon because I think he will be a good addition to the Connollys, the Defoes, the Carricks, the Mullins, the Pearces and the Daillys - and as yet I am not got getting nine out of ten performances out of them."
The 4-3-3 system that Trevor Brooking employed to such effect in his time as caretaker is something that Alan is a fan of and he adds:
"I am just looking at the way teams are set up; we instigated it at Reading and most of the teams in the division are adopting it and although you can hit teams on the break it leaves you defending long periods of the game.
"If you have enough strike force in the team then you can take the game away from them and that is what I intend to do.
"But we haven't won a game yet and we have some tough games coming up without Defoe, so Marlon was an important capture just for this next period.
"It wasn't great last night because of the size of the pitch - but when we have a bit more room I am hoping we get a bit more joy out of our passing and a better rhythm to our game; it was difficult to get any rhythm out there on the night."
