Wigan Athletic boss Roberto Martinez is dead against his players using pills.
He has warned Roy Hodgson that England are gambling on playersâ€™ futures by dishing out sleeping pills.
And the Wigan manager said dosing them up on energy tablets is just as risky â€” calling it â€śa step into the unknownâ€ť.
Martinez is one of the gameâ€™s most knowledgeable and well-read bosses on the value of diet and nutrition.
He said: â€śFootballers need to train well and to sleep well â€” eight hours.
â€śBut Iâ€™m not a big lover of sleeping pills as you canâ€™t be sure of effects further down the line.â€ť
