Ajax being linked with Benfica keeper Vlachodimos

According to reports coming from Portugal Dutch side Ajax are interested in landing Benfica starting keeper Vlachodimos next summer to replace their current starting keeper Andre Onana who looks set to depart with links to some of Europe's bigger clubs.
Vlachodimos who joined Benfica in the summer of 2018 for €2.5M from Greek club Panathinaikos is the replacement that Ajax favour but Benfica would not let their current number one depart for anything less then €15M. Vlachodimos has appeared in 72 games across all competitions since joining Benfica and has kept a clean sheet in 44% of the games for 32 in total. Benfica have spent the past 6 months looking for a keeper to battle Vlachodimos for the starting job but have yet to land that said keeper and the Greek International is currently being backed up by 22 year old Ivan Zlobin.
