Dutch giants Ajax have signed striker Chuba Akpom from Championship club Middlesbrough in a deal worth up to 14.3m euros (£12.2m).
The 27-year-old is yet to feature this season but finished last term with 29 goals for Boro in all competitions to finish as the second tier's top scorer.
It was the ex-Arsenal striker's best career return, with a total of 106 goals in 309 senior matches.
"I'd like to thank everyone connected with Boro," Akpom said.
"Last season was full of memories I'll never forget and I will be forever proud. Everyone knows what I think of [Middlesbrough boss] Michael Carrick, and I'm sure success is just around the corner.
