Mane played around 5/600 extra minutes.
Though all of Manes goals are in the CL or league as are nearly all his minutes. 9 of Nunez are in FA,League cups,Europa league and Community shield.
As I said he also joined a far better team and is a striker.
He can't be relied on to score goals when the chips are down, he simply isn't good enough and at nearly 25 he isnt going to develop much either. As I said earlier scoring st a similar rate to Gordon,Richarlison and has been outscored by Chris Wood. No excuse for service either.
