Chuba Akpom has completed a move to Ajax from Middlesbrough.
The 27-year-old forward was the Championship's top-scorer last season with 28 goals to help Michael Carrick's side finish fourth, reaching the play-offs where they were beaten by Coventry.
Former Arsenal trainee Akpom was in the final year of his contract with Boro, and his switch to the Dutch giants has been confirmed as a £10.5m (€12.3m) deal. Ajax said amount can increase to £12.23m (€14.3m) through variables.
Akpom, voted the Championship player of the year for last season, said on the Middlesbrough website: 'I'd like to thank everyone connected with Boro and especially a big thanks to the fans for the support and love they have given me.
