"It is hard because I didn't have much of a pre-season in terms of games - but I am feeling fit and stong and ready to go on Saturday," says Luke.
"I think I am just catching up now - I am feeling good now and ready to start playing really well, I hope."
Luke had an extended loan spell at Burnley, and he knows a thing or two about them.
"They have started the season very well; they are unbeaten but they have drawn a few games and they have a strong defensive unit - it will be tough to break them down.
"I am sure if we play our best we have got a great chance of winning the game.
"I had a good time and made a lot of friends there - it will be good to catch up with the lads on Saturday.
"Steve Cotterell is there now, a good young manager, and it will be an interesting game."
He feels the loans he enjoyed at Burnley and Reading have stood him in good stead, and he explains:
"Without a doubt it helps you when you are playing regularly; it was a good learning curve for me at Burnley but I am a West Ham player now and eager to do well here.
As for Tuesday night, he admits:
"It was a tough game; I thought Southend acquitted themselves very well but in the end we were too strong for them and got a 2-0 win.
"They are always hard matches and it was a massive game for them - lower league teams always raise their games but we scraped through in the end.
"We won at Crewe, we beat Southend in the Carling Cup, and we just need to keep winning now to get a good run - and up towards the top of the table."
Luke is delighted that Marlon Harewood is on the score sheet again after Tuesday night and he says:
"Marlon played really well against Crewe and then again on Tuesday when he scored the two goals so it is great for him and it will be great for the team if he keeps at it."
