Swindon manager Paolo Di Canio has admitted to pushing his players to the maximum before the coming season, and believes it is vital that the recently relegated Robins have the mental fitness to boot.
The former Italian international, who joined the club at the end of last season as Swindon dropped into Npower League Two, revealed that the squad had faced some gruelling sessions.
"This is the way to train, it may be a hard moment now but if we can make sure that despite fatigue the brain is still strong, then this is the correct way," said Di Canio.
"It is difficult I know, also for the top players, but we have to accept with this situation the players will become better individually and a better squad together.
"If they can handle this situation now, then they can handle it in the final five minutes of a real game," he continued.
"When you are tired but your brain still concentrates, then you win the game, because you still make the correct moves and correct decisions and secure the victory.
"The direction Swindon drove in last year was the wrong one and we must change this. If we kept the same team we would go down again.
"If a team who goes down keeps the same players with the same attitude and tries to go up, they will only go lower. Teams with perceived less quality will hit you because they have the desire to do so.
"Therefore everything had to be changed. Our regime of discipline and a very straight, defined direction is the best way."
