Arsenal in advanced talks to sign Sporting striker Viktor Gyokeres

Arsenal are in talks to sign Sporting's prolific Sweden striker Viktor Gyokeres for £70m.

As first revealed by BBC Sport on Thursday, Arsenal have had a clear focus on completing a deal for the 27-year-old in recent days and the club are now advancing in their pursuit of the forward.

Discussions over personal terms for Gyokeres and with the Lisbon club over a transfer fee are accelerating, with Arsenal's sporting director Andrea Berta leading negotiations.

A deal has not been finalised though, and there remains a degree of caution at Arsenal until agreements are reached.

Gyokeres has been heavily linked with a move to the Premier League after scoring 97 goals in 102 matches during two seasons in Portugal.

The Gunners completed the £60m signing of Martin Zubimendi from Real Sociedad on Sunday.

But the movement towards a deal for Gyokeres represents a significant development in Arsenal's summer transfer business given a new striker was the club's main priority.
