Liverpool agreed to sell c for 35 Million Euros to Leverkusen, I don't know if this is a lose for Liverpool or not. His value is actually fair for 35 Million Euros because his performance isn't that good even he had been played for 2 years in Liverpool.
But, Quansah might able to improve and upgrade his level because he' still young.
he gets talent and has the potential to develop, but the offer from Leverkusen to buy Quansah may be too tempting for Liverpool, and it makes them want to release one of their talented young players. and the matter of rejuvenating the squad may be a consideration in the process of transferring Quansah to Leverkusen, because now Liverpool is eyeing one of the best center-backs in the English league and it encourages them to release Quansah who has now started playing less for Liverpool.
And he is still young, so he still has plenty of time to improve at Leverkusen and start a better career there.
