Adam Lallana has completed his £25m move from Southampton to Liverpool.

Lallana, 26, completed a medical at the weekend and is manager Brendan Rodgers' second summer signing, joining former team-mate Rickie Lambert at Anfield.

The midfielder, who was part of England's World Cup squad in Brazil, made 265 Saints appearances and will take Liverpool's number 20 shirt.

"I am so excited for the next chapter of my career, coming to a special club like Liverpool," said Lallana.
