The young attacker will continue his career in Russia after impressing in the Eredivisie last season
Spartak Moscow have completed the transfer of Netherlands international Quincy Promes from Twente for a fee believed to be in the region of €15 million.
Both sides had already reached an agreement earlier this week and the attacking midfielder, who can also play on either wing, has now signed a contract until the summer of 2018 with Spartak after passing his medical.
Promes burst onto the scene in the Eredivisie last season with 11 goals in 31 appearances as Twente qualified for the Europa League with a third-placed finish.
His form attracted the attention of a number of clubs and it seemed certain he would stay in Enschede after signing a contract extension, but Spartak have managed to secure his signature and Promes is looking forward to the next chapter in his career.
"I am happy that all the formalities are settled and I am now a Spartak player," he told the club's official website.
"For me as a young player, this move is certainly a step forward.
"Here I get the opportunity to grow and develop as a professional, playing in a strong league, and I hope to be able to benefit from a new team.
"This is a very big club with a great history."
The 22-year-old made his Netherlands debut against France at Stade de France in March and was also included in Van Gaal's provisional squad for the World Cup in Brazil, although he failed to make the final 23.
