Arsenal have reached a full agreement with Sporting CP for the transfer of Viktor Gyokeres. The Premier League side will pay an initial €63.5million (£54.8m; $74.2m) plus €10m in add-ons. Gyokeres has been given permission to travel by Sporting and is expected to undergo his Arsenal medical on Saturday.

Though Gyokeres is likely to play a couple of friendlies for Arsenal in the build-up to the new Premier League season his first, full debut for the club will be on the opening weekend of the season. Arsenal take on Manchester United at Old Trafford in the headline match on Sunday 17 August with kick off at 4.30pm BST.

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.
