Arsenal are in the process of completing a deal to sign Viktor Gyokeres after taking final steps in negotiations with Sporting CP for the striker. Talks have been prolonged by Sporting president Frederico Varandas refusing to accept what Gyokeres believes was an agreement to leave this summer for €60million plus €10m of add-ons.

Gyokeres has already agreed personal terms on a five-year deal and has been awaiting a club-to-club agreement. He is now expected to join Arsenal in a deal worth €63.5million (£54.86m), with a further €10m (£8.64) in add-ons.
