Brentford boss Thomas Frank admits David Raya will be staying with Arsenal.
Raya moved on-loan to the Gunners this week with a permanent option.
"I think that this is a deal that will be complete in the future," Frank said.
"I think it will not be a loan in the future, that is my feeling and understanding because I don't think it makes sense to go there on loan where there is big competition for the number one spot.
"Of course I back him, I think he is a fantastic keeper, maybe I'm slightly biased but I think he is a very good keeper."
