Grasshopper Club Zürich and Wolverhampton Wanderers
On 8 July 2021, he signed a 3-year contract with Grasshoppers in the Swiss Super League.[6] Due to delays with his work permit,[7] he only made his debut on 7 August 2021 against Lausanne-Sport, being named in the starting lineup and playing 60 minutes.[8] He scored his first goal in a 3-1 away victory over FC Sion on 31 October 2021, scoring the opener in the 32nd minute[9]
