According to the Sunday Mirror, all three clubs are tempted by the Senegal international who has impressed ever since joining Liverpool from Southampton.
Mane has three goals in four Premier League outings this season already and his devastating pace, power and goalscoring ability makes him a highly exciting attacker.
The report also states that Barca’s interest in Mane means they are willing to finally give up on Coutinho.
However, if Barca found it tough going trying to sign Coutinho, going for Mane will probably be even more difficult, with the forward arguably emerging as the Reds’ most important player.
The 25-year-old scored 13 goals in 29 appearances in his debut season for Liverpool, although it’s worth noting his season was ended prematurely due to injury.
He also scooped the club’s Player of the Season and Players' Player of the Season awards - highlighting just how highly he is valued at Liverpool.
