Frenkie de Jong is one of the many young prospects that Ajax have produced in recent years. De Jong came under the radar of many big clubs after his successful 2018-19 season where Ajax won the domestic double and had a fairytale run to the Champions League semi-final. Barcelona signed the 22-year-old for a reported fee of €75m.
Rodri joined the Premier League champions Manchester City from Atletico Madrid for €70 million. He will strengthen the already strong side which won the historic domestic treble last season.
Rodri's choice to leave Atletico is a big gamble for his career as he may not get as many minutes at Manchester as he did at Madrid.
Tanguy Ndombele joined Tottenham Hotspur for €60 million from Lyon, with Tottenham entering the transfer market after being absent for the last two windows. After a successful season with Lyon, Ndombele even made his national team debut for France as a substitute in a friendly match.
