Viktor Gyokeres' father was reportedly reduced to tears upon hearing that his son's move from Sporting Lisbon to Arsenal may collapse at the final hurdle.
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.
