The Reds confirmed the Southampton captain's signature earlier this morning, with the transfer fee reported to be around the £25 million mark.
Lallana will wear the number 20 and says he dreamed of playing for a 'special club' like Liverpool, with the move providing an 'exciting' new chapter in his career.
Former England and Tottenham striker Gary Lineker reacted immediately.
Lallana is an excellent signing for Liverpool. A delightfully gifted, beautifully balanced footballer.— Gary Lineker (@GaryLineker) July 1, 2014
Last season, the 26-year-old played in every one of Southampton's Premier League games, scoring nine times and registering six assists. That form got him into England's World Cup squad, so it is no surprise Lineker is impressed.

As Opta stats show, Lallana also created five big chances and made 36 accurate crosses. Even more impressive, however, was his dribbling ability, with the Saints midfielder having won 70 contests on the ball.
Questions may be asked of the England man's reported fee - but he can play virtually anywhere in attacking midfield, perhaps prompting Lineker's claim that Lallana is 'beautifully balanced.'
On Southampton, Lineker had a more somber view.
Must say, I do feel for Southampton's fans. A lovely team is disintegrating before their eyes. All the best, Ronald.— Gary Lineker (@GaryLineker) July 1, 2014
Indeed, the Saints are now left without three of their stars of last term, with Luke Shaw having moved to Manchester United and Rickie Lambert also completing a move to Anfield this summer.
The club have reportedly recouped close to £60m for the trio, however, leaving Ronald Koeman and the board plenty of money to build for the future.
As for Lallana, he now knows he has the backing of Liverpool Football Club and an England legend.
