The striker has signed a long-term deal, reportedly a five-year contract, at the Emirates in a £63.5m (€72.6m) move, including add-ons, from Sporting CP

After months of speculation, the club have agreed a €63.5m fixed fee with a further €10m in add-ons for Sporting CP's free-scoring striker

Despite agreeing the basic framework of a move for Gyökeres weeks ago, Arsenal and Sporting found themselves butting heads over the nature of the add-ons proposed by the Gunners, which invited pressure of a potential hijack from long-term admirers Manchester United.
