Arsenal changed a lot in the 22 years that Arsene Wenger was in charge of the club, including his methods on player fitness.
When he came in to the club, the likes of Tony Adams and Paul Merson were known for their partying lifestyle and poor diets.
The Frenchman implemented a complete change to the diet of the players and is credited with bringing about the importance of nutrition that has become the norm at the highest level.
Now, his predecessor is taking things to another level, as he has reportedly banned his players from drinking fruit juice according to the 'Mirror'.
Emery got his first win of the season against West Ham last weekend, as he looks to finish in the top four in the Premier Leafue table come the end of the season.
