Arsenal sporting director Andrea Berta has held face-to-face talks with Sporting in Portugal as the Premier League club move closer towards a deal for striker Viktor Gyokeres.
BBC Sport revealed last Thursday the Gunners had accelerated their interest in the Sweden international as their well-documented search for a new centre-forward reaches a climax.
And well-placed sources have indicated that process saw Berta fly to the Portuguese capital towards the end of last week for key discussions with Sporting counterparts over a deal that could be worth around £70m.
It is unclear if he returned to London over the weekend, but Berta's Portugal trip provides a clear indication towards the level of Arsenal's desire to finalise a deal quickly for Gyokeres.
