Arsenal defender Gabriel Magalhaes has delivered his verdict on the club's top target and Sporting Lisbon striker Viktor Gyokeres.
Mail Sport understands that the clubs are close to agreeing a deal worth an initial £55million, with a further £7.4m in add-ons, while Gyokeres has agreed a five-year contract.
Arsenal had hoped to seal the deal before they flew out to their pre-season tour of Asia on Saturday, but the two sides remain at odds over bonus payments and the schedule of instalments, with Sporting pushing for more of the fee up front.
