The report stresses that Arsenal and Gyokeres’ camp presented a deal that guaranteed Sporting a fixed sum of €70million (£60.8m) plus €10m (£6.95m) in add-ons. However, the dialogue between the three parties hit a roadblock on Monday and negotiations are ‘at risk of collapsing completely’.

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. Sporting confirm a deal in principle is in place, with an agreement of a €63.

Arsenal expect to reach a full agreement with Sporting inside the next 24 hours for the 73.5m euros (£63.5m) signing of Viktor Gyokeres.
