Quincy Promes has left Sevilla and completed his move to Ajax.
The Champions League semi-finalists are paying 15.7 million euros for Promes, significantly less than the 20.8 million euros that Sevilla paid Spartak Moscow for the winger last summer.
However, with variables, the transfer could reach up to 17.2 million euros plus a percentage of a future sale.
It is Sevilla's second big sale of the summer window after having recently sold Luis Muriel to Atalanta for just over 18 million euros.
