🚨Paul Merson tips a potential Arsenal double win as the greatest achievement in British football history. 🗣️“I’ll tell you something, if Arsenal manage to win the Premier League and Champions League this month, it’ll be the greatest achievement we’ve witnessed in British football history, I genuinely believe so. “I think it will be a better achievement than City’s centurions, better than United’s treble winning season as well as City’s. None will come close really” “Winning both competitions after such a barren spell will be an extraordinary feat. No team has done that before, absolutely no one!”
