The veteran is out of contract in the summer, but wants to focus on having a great end to this term.
Lallana told The Argus: I'm fit and well. I hadn't featured from the start for a little while before Spurs but I've been well.
I'm enjoying the moment, enjoying where the football club is at and being part of it.
I don't take any sessions for granted at the minute.
Who knows what's around the corner?
I don't think I want to make the decision yet.
I want to enjoy the back end of the season because it could be special, you know?
"We could go deep in two competitions, we've got the league there as well.
I have learned throughout my career that it is important to enjoy these moments rather than look too far ahead into the future.
Time goes fast so enjoy things."
