Sevilla are concerned about Arsenal activating Grzegorz Krychowiak’s release clause, according to the Metro website.
The Premier League giants have been linked with a £21m move for the Polish midfielder over the last few weeks as Arsene Wenger seeks to bolster his midfield.
And there will be nothing Sevilla can do about it if Arsene Wenger activates his get out clause.
Krychowiak’s team-mate Vicente Iborra admits losing him is a worry.
He said: “Of course I am concerned that Krychowiak could be taken away.”
