Reports on Thursday suggest Barcelona and Juventus have joined Paris Saint-Germain in the race to sign the 28-year-old this summer.
Seven goals and seven assists in 20 Premier League games proves Lallana's influence at Anfield - and he ably stepped up during the seven-week absence of Philippe Coutinho.
Lallana has been in impressive form under Klopp, scoring seven times in 18 Premier League appearances for Liverpool this season, helping them challenge Chelsea at the top of the table.
Juventus are also being linked with Liverpool midfielder Emre Can.More news: Are Selena Gomez and The Weeknd Dating?
The challenge for Lallana will now be to maintain his impact alongside Coutinho - but this, coupled with the latest gossip, shows just how far the England worldwide has come.
Lallana still has two years left on his contract and has already stated his intentions of staying Anfield for the long term despite interest from PSG in the summer.
Lallana's contract expires in June of 2019, and the Times is reporting that his form has attracted the attention of some of Europe's biggest clubs.
Juventus are also monitoring the England worldwide and will consider a move if they are unable to lure Alexis Sanchez from Arsenal. And interest from FC Barcelona and Juventus speaks volumes of the kind impression the English midfielder has made over the last couple of months.
