Southampton captain Adam Lallana will undergo a medical at Liverpool this afternoon ahead of a £25m move to Anfield.

Wide ranging reports suggest Lallana, 26, will become the second high profile departure from St Mary's in the space of 24 hours after Luke Shaw completed his move to Manchester United for a fee that could rise to £31m.

The England international is reportedly travelling to the club's Melwood training facilities to have a medical and seal a move that will see him link up with Rickie Lambert, who left Southampton for Anfield at the beginning of the month.

Lallana would become Brendan Rodgers' third addition to the club this summer following the arrival of Lambert and midfielder Emre Can from Bayer Leverkusen.

Press Association Sport suggests Lallana's move could be completed imminently.

The Merseyside club are understood to have seen a number of approaches for the midfielder turned down following the conclusion of the 2013/14 campaign, when Lallana helped guide Saints to eighth in the Premier League.

The Liverpool manager has been keen to sufficiently bolster his squad ahead of the new season where he will be expected to strike a balance between European and domestic commitments, and it is understood his latest addition could be confirmed as early as Friday.

Lallana will end his 14-year association with Southampton having played an integral role in the side during their rise from League 1 back to the summit of English football.

Bournemouth, who briefly had a 12-year-old Lallana on their books, are also set to profit from any deal after including a sell-on clause in the deal that saw him join Southampton in September 2000.

The Cherries will receive 25% of the fee Southampton receive which would see the Championship outfit receive a cash windfall of £6.25m.
