I dont think so. Mane isn't overprice. He doing great in Soton last season.and he deserve his price.
And Wijnaldum, althought newcastle is a relegation team, but he scored 11 goals, more than Pogba in serie a, and pogba's price is 120m
Who is overpriced?
Already, Pogba is a defensive midfield and Wijnaldum is an attacking midfielder. And you know, the talent of a player is not his number of goals scored.
