Arsenal coach Unai Emery believes it is necessary to pay attention to details to try to improve the team's performance. The Spanish specialist banned fruit juices, and also decided to introduce more intensive training in the wild.

Emery's tactics require a high degree of physical fitness, so the new coach of the "Gunners" has tightened the rules.

Since arriving in Arsenal, Emery scored only one victory in the Premier League - in the third round against West Ham (3: 1). In the first two rounds he lost to Manchester City and Chelsea.
