The England midfielder was part of the side held to a goalless draw at The Hawthorns, a result that left Brendan Rodgers’ side seven points off the top four with five games to play.
The first of those is away at Hull on Tuesday, and Lallana is confident maximum points from their remaining games would be enough to salvage a fourth-placed finish.
“We’ll dust ourselves down, go again, go to Hull and try to get three points to hopefully put as much pressure on the teams above us as possible,” he said.
“I still feel that if we pick up maximum points from the remaining games,??we’ll be unlucky not to get into that fourth spot. It’s still possible and while??it’s still possible, we’ll keep giving our all.
“We’ve just got to focus on ourselves. It’ll be a difficult place to go -??they’re still fighting for their lives down at the bottom.
“It will be a tough game, but we’ve got to go there and play our game and??hopefully we’ll get three points. You want to get back to winning ways as??quickly as possible.”
