10 best signings under £50m this summer, featuring Arsenal, Liverpool & Chelsea bargains

1) Mamadou Sangare – £39m

Already hyped up as one of the signings of the season for just £39m by Sky Sports, Mamadou Sangare has made a bright start at Brentford and looks like yet another player they’re likely to sell for a considerable profit at a later date. For now, though, he’ll surely be key for the Bees as they once again look to establish themselves as a safe top half team and perhaps even challengers for a European place.
