Viktor Gyokeres is said to refuse to appear for training for the season with Sporting Lisbon while he insists on a move to Arsenal.
It is thought that the Swedish International agreed on the conditions for the Gunners after priority to relocating to North London above Manchester United.
The striker is of the opinion that he has an honorary agreement that enables him to leave the club for a reimbursement of € 60 million, plus another € 10 million (£ 51.7 million plus £ 8.6 million).
Despite the fact that Arsenal reportedly offers € 65 million, plus another € 15 million (£ 56 million plus £ 12.9 million), but the Portuguese club is now supposed to be strong at a fixed € 70 million (£ 60.4 million).
Gyokeres would report on Friday for training for the season with Sporting, but according to the Athletic he will not appear.
It is said that he feels betrayed, convincing that President Frederico Varandas broke a pact to make him leave for a figure where Arsenal has already been surpassed.
After conversations came to a halt last weekend about the issue, such as according to Portuguese Outlet A Bola, it has now been some time since the two parties discussed the transfer.
The break in the procedure could still mean the worst in front of Mikel Arteta and for Gyokees, who is said to be so enthusiastic about a move to Arsenal that he is approaching that he does not return to the training for the season with the club in Alcochete on Friday.
Arsenal Sporting Director Andrea Berta led the Arsenal delegation that flew to the Iberian peninsula for conversations with the Primeira Liga side, alongside Gyoke's agent Kenan Mert.
A Bola claims that Mert claimed that former sports director Hugo Viana – who is now at the Premier League rival Manchester City – offered the player a guarantee that he could leave during this summer's window.
The impasse could be for the Gunners, where the deal looks increasingly challenging to cross the line.
The former Coventry City and Brighton Striker currently still have three years on his contract with the Portuguese giants, although it seems unlikely that he will see those conditions if things are standing.
The Swedish International scored a stunning 54 goals for the Portuguese giants in the past term in all competitions.
The Gunners have already signed midfielder Martin Zubimendi of Real Sociedad for £ 60 million, goalkeeper Kepa Arrizabalaga from Chelsea for £ 5 million and have reportedly completed a £ 12 million step for Brentford Captain Christian Norgaard.
They are also about to complete a movement for Chelsea Winger Noni Madueke and are connected to Crystal Palace Talisman Ebereechi Eze.
