Liverpool legend Carragher has claimed on Twitter that Mane’s price-tag, which he believes is £30m, is too much.
However, the former England international defender has stated that he likes the 24-year-old as a player.
Liked Mane at Southampton but I do think 30 mil is expensive but if he delivers it'll be worth it like every transfer. It's 30 not 38.5 mil!— Jamie Carragher (@Carra23) June 27, 2016
Mane scored 11 goals and created 41 chances in 37 Premier League matches for Southampton during the 2015-16 season.
