Ajax have signed Steven Berghuis from Feyenoord on a four year deal, the club announced on Monday.
The Dutch international’s move has caused controversy in the Netherlands due to rivalry between the two sides, especially between their fans.
Berghuis, who was under contract with the Rotterdam side until mid-2022, said in a statement that he wanted to move to develop his game further.
“I am 29 years old, and it’s no secret that I wanted to take the next step,” Berghuis said.
“It is important to me to further develop myself in the sport. When making the choice for my new club, in addition to my development as a football player, I was very much looking for the combination of playing for trophies, playing in the UEFA Champions League and staying in the picture with the national team. At Ajax I think this all coincides.”
