The Leeds midfielder remains positive in the face of back-to-back pre-season defeats.
Indeed, Leeds lost their last two friendlies to Eintracht Frankfurt and Hoffenheim and are yet to register a win in pre-season but, like many, midfielder Mowatt is refusing to pay attention to the scoreline during the Yorkshire side's friendly schedule.
The 20-year-old is instead concentrating on the amount of running and work the Leeds players were able to put in during both of their 2-1 defeats and has pinpointed the condition that should allow Rosler's high-pressing game to work.
Indeed, it's simply down to fitness according to Mowatt.
That may be an old line to peddle, of course, as Rosler has continually emphasised how much fitness work Leeds have done throughout pre-season - meaning one would assume United should be up to speed in that area if anywhere.
But it may be a bit soon to criticise the Whites' form and Mowatt is sure the Leeds' squad's ability to adapt to their new coach's tactics will improve with time.
Mowatt is quoted as saying by the Leeds site: "They were both good teams - they both got it down and passed it. We had to do a lot of running and we didn’t have a lot of possession.
"It was good to go out there. We did a lot of hard work and I think it showed in the first half on Saturday. Everyone’s fitness is getting better and when we’re fitter the high-press game will work better."
