Liverpool are reportedly fearful that Sadio Mane could leave the club during this summer's transfer window.
The 28-year-old has again been in excellent form for the Reds during the 2019-20 campaign, scoring 18 times and contributing 12 assists in 38 appearances in all competitions.
Mane still has three years left to run on his contract at Anfield, but according to The Sun, the Senegal international has been offered a new long-term deal by the European champions.
The report claims that the attacker is 'yet to offer any indication' that he will pen fresh terms with Liverpool, and head coach Jurgen Klopp 'is growing anxious over the situation'.
Real Madrid and Paris Saint-Germain are both said to be closely monitoring developments as they weigh up a move for the left-sided forward during this summer's transfer window.
Mane has scored 77 times and registered 34 assists in 161 appearances for the Reds since arriving from Southampton during the summer of 2016.
