Ajax Amsterdam is one of those clubs in Europe that are always able to bring out good new and young players almost each season. Only this season they have sold Ryan Gravenberch to Bayern Munich and also lost Mazraoui to them after they did not manage to prolong the contract with him and in the years before they have sold Frenkie de Jong and Matthijs de Ligt for huge amounts of money to Barca and Juventus.
This have brought Ajax Amsterdam a lot of money, but of course this is also a problem. They can never really hold their squad together because Ajax is simply no Tier 1 club at the moment so their best players are always leaving for the biggest clubs. It's the same with Antony and Jurrien Timber.
