Mertesacker: Arsenal players fully behind Wenger
Arsenal sit 15th in the table, with Mertesacker coming in for criticism for some of his performances.
"He gives this feeling to everyone on a daily basis. This knowledge gives me a lot of security.
"He (Wenger) has a huge reputation there and enjoys complete confidence.
"For the Arsenal fans Wenger is a hero and he cannot lose this status. There is no one here who is not certain that the success will return.
"We have a talented team with a lot of potential lying dormant within us and it's only a matter of time before that comes to the surface."
