Arsenal transfer plans: Isak, Gyokeres and Zubimendi on list

Arsenal have alternative targets to Isak – namely RB Leipzig’s Sesko and Sporting’s Gyokeres.

Sesko is a long-term target and was close to joining the club last summer.

Arsenal enquired again in January, but the German club were adamant they had no intention of selling and the Gunners did not want to antagonise them before a potential negotiation this summer.

Slovenia international Sesko has scored 26 goals this season – already an improvement on the 23 he hit last year. At 21, he fits the ideal age profile for Arsenal in terms of financial and technical growth.

But the appointment of Berta has resulted in Gyokeres’ stock rising, with sources in recent weeks indicating there is considerable internal backing for a move for the Swede, despite much of the groundwork having been completed on a deal for Sesko.

Both players have release clauses, but the indications are their clubs are willing to negotiate lower fees.

At this stage, sources suggest Gyokeres, who has scored 38 league goals this season, is the most economical signing of the two.

But prior to Berta’s arrival there were concerns whether Gyokeres’ form in Portugal would translate to top-level performances in the Premier League.

Similarly, the fact he will turn 27 before next season presents a financial dilemma given the likely outlay.

Arsenal are also looking to sign a winger, with Athletic Bilbao’s Nico Williams a genuine target.

The Spain international has a reported 58m euro (£49m) release clause, but his wages would make him one of the biggest earners at the club.

Borussia Dortmund winger Jamie Gittens has also been liked with the Gunners.
