This has been a fine campaign for the 26-year-old, whose wonderful performances saw him nominated for the Professional Footballers' Association Player of the Year award and named in the team of the season.
This week Lallana cleaned up at Southampton's annual awards and the attacking midfielder is set to be named in Roy Hodgson's World Cup squad on Monday - less than 24 hours after what is being billed in some quarters as his last match for Southampton.
The academy graduate has been heavily linked with a move to Liverpool and some interpreted the emotional nature of his awards night speech on Tuesday as a hint that his future lies away from St Mary's.
"I got emotional because it's been a journey that I couldn't have dreamed of - but I'm not saying that this is the end by any means," Lallana told the Southampton matchday magazine ahead of the match with Manchester United.
"Obviously, with how well the club and its players have done, there are going to be some decisions to make in the summer, and maybe it all hit home a little bit when I was speaking.
"How far we've come in a short space of time is beyond anyone's belief. We've won our league, in our eyes, with where we've finished.
"We're now in a position where we have to sit down as a club and decide what is best and what's the right route to take, because we want to be a stable club - that's the main thing.
"We want to be competing in the Premier League for the next four or five years and forever longer."
Lallana is not the only big name to have been linked with a move away from Saints, with teenager Luke Shaw and manager Mauricio Pochettino also attracting admiring glances.
"I just want to be honest," Lallana added.
"I feel I've been honest throughout my whole career and I want to be honest now to whoever I'm speaking to, whether it's the fans, the manager or anyone.
"Every fan would realise that there's big potential in our team and we have players who can go and play at a higher level - we proved that when there were 16 of our lads away on international duty.
"I'm certainly ambitious. I want to one day play in the Champions League and compete for the Premier League title, but I still feel like I'm the same guy I was when we were playing in League One and the Championship.
"I haven't changed my personality or changed as a person. It's a privilege to be in this position and I wouldn't change it for the world."
