The Mexico forward spent the last half of the season on loan at Sevilla from Porto.
Layun is keen on going back to La Liga giants but believes the feeling isn’t mutual, giving the Gunners a great chance to pounce.
The 30 year-old has been representing his country in this summer’s World Cup and scored against Germany in their 2-1 win over Germany 10 days ago.
It appears the ex-Watford forward’s proposed permanent switch to Sevilla is in unlikely to go through.
As reported by The Sun, Layun revealed that although he would love to return to southern Spain, he believes the feeling may not be mutual.
Layun said: “I’m just like everyone, waiting for something to be confirmed. In a tournament like the World Cup I’m totally focused on what I want to achieve here, but of course there is always that issue of not knowing what will be of my future.
“Participating at such an important club in Europe was very special. I expressed that it would be a dream to be able to continue with the team.
“I still haven’t ruled out the possibility of staying at Sevilla, because for me it would be very nice.
“It’s complicated. But I think if they had the intention [to sign me] they would have already communicated with me and with my agent.”
