Rickie Lambert arrived at Liverpool's Melwood training complex to undergo the procedure after staying at a city centre hotel on Friday evening, and looks to be on the brink of signing for £4million from the Saints.
So what will the England international bring to the Reds next term?
Lambert has been unfairly pigeonholed as a traditional target-man striker, who can count his strength and aerial ability as his main attributes.
How people have reached the conclusion of Lambert as an old-school traditional number nine who has a 'good touch for a big fella' is stereotyping at its worst.
The Saints striker is a clever forward, who continually drops off the defenders to receive the ball and play in attacking midfielders, who were encouraged to run beyond once Lambert had dropped off at Southampton.
That intelligence can only benefit Luis Suarez and in particular Daniel Sturridge next term, and Lambert's clever nature can see the side thrive.
The England international is also a big step up from Iago Aspas, who failed to justify his modest £7 million fee after moving from Celta Vigo last summer.
Aspas's biggest contribution in red was a goal against Oldham Atheltic in the FA Cup, and a contender for the worst corner of all time against Chelsea at Anfield.
While Liverpool did not often need a third option due to the superb displays of Sturridge and Suarez last term, they certainly did against Jose Mourinho's side last month, and Lambert will provide the Reds with a good alternative, while also accepting that he is very much behind the 'SAS' in the Anfield pecking order.
Meanwhile, Lallana, who is the subject of a £25million bid from the Reds can provide Philippe Coutinho with some stiff competition for the role of play-maker in the side.
Manager Brendan Rodgers likes to alternate between a 4-3-3 formation and a 4-4-2 with a diamond shape, and Lallana can certainly flourish at the tip of the latter's set-up.
With Suarez and Sturridge's movement ahead of him, Lallana will be given ample opportunity to rack up the assists and catch the eye along the way.
Given license to roam, the 26-year-old, who netted nine times for the Saints last season, can add even more creativity to a side that plundered 101 goals last term.
