Arsenal boss Arsene Wenger is bracing himself for a season that, dependent on its outcome, could mean a rethink of strategy at the end of the campaign.

"I refused [Real Madrid] because I have built a young team and I have the feeling that I have not finished my job," Wenger told French radio station RMC.

"I am not denying it will be a decisive season. If we are not in the title race, we will have to build everything again."
