Liverpool reportedly intend to block any planned move from Bayern Munich for forward Mohamed Salah at the end of the season.
Bayern chief executive Karl-Heinz Rummenigge admitted in an interview earlier this week that it would "be an honour" to sign the 28-year-old.
Rummenigge also described Salah as "the Lionel Messi of Africa", only strengthening rumours of a possible move to the Allianz Arena in the summer transfer window.
However, The Sun claims that Liverpool have issued a hands-off warning to the European champions by reiterating that the Egypt international is not for sale at any price.
Salah still has another two-and-a-half years to run on his Anfield contract, which is believed to be worth in the region of £200,000 a week.
The former Chelsea and Roma attacker leads the way at the top of the Premier League scoring charts this season with 16 goals in 22 appearances.
