Rickie Lambert earned his debut call-up against Scotland last year, and Lallana wants to see the group maintain their focus for the Saints if they are to stand any chance of being selected for the Brazil tournament.
He told Sky Sports News: "The fact that we could have four players involved is great you know, but we're just thinking about our club form and concentrating on that.
"We'll have to try and stay fit and we'll just have to wait and see what happens. We want to make (England boss) Roy Hodgson's life harder by playing as well as we possibly can for Southampton.
"It'll make his decision even harder and if we can all be involved then great."
The quartet were involved for the side that were beaten 3-2 by Tottenham Hotspur this afternoon.
