"I promise that this club will have fewer injuries than it used to," he told reporters. "We have worked hard on fitness,and fitness levels are all-important if you are to maintain quality for long periods of the game and for many games, consistently.
"The majority of the squad had just one day off training all summer but I think this is a good thing because, in my view, if you train hard, you have less, not more, chance of injury.
"Of course we will have an injury or two at some stage, I'm not saying we won't but what I am saying is that, with the fitness levels we have, we will pick up far fewer injuries over the course of the season and that has got to benefit us in the long run."
Sunderland currently have five players out due to injury, two of them - Wes Brown and Cattermole - long-term absentees.
