LONDON (AFP) - Arsenal manager Arsene Wenger said on Wednesday that his side's interest in Luis Suarez was "on standby", after the unsettled striker called on Liverpool to let him leave.

The 26-year-old says he cannot afford to spend another season without playing in the Champions League, but Arsenal are running out of time to include him in their squad for a play-off tie later this month, as squad lists must be registered with European governing body Uefa by Aug 12.

"At the moment the situation is on standby. I heard that (Suarez is considering legal action), but this is sometimes linked with things that you don't know as a potential buyer," Wenger told Al Jazeera Sport.

"That is the story between Suarez and Liverpool and I don't know what has been said, what has been promised and what has been written, and that is only Suarez and Liverpool that can decide that.

"It is nothing to do with us. We have been told that the player wants to leave Liverpool and that is why we have acted. I really don't know what will be decided by Liverpool."
