Manchester United midfielder Ander Herrera insists their preseason defeat to Borussia Dortmund isn't a concern.
United are focused on a longer term target - which is winning the FA Community Shield next month.
"We are a team and we all want to be fit as soon as possible," Herrera told MUTV.
“That is why we are working so hard in these days. Just yesterday, we trained two times so you can feel it on the pitch but, of course, we want to be ready for Leicester and we want to win the first title of the season. So that is the most important thing, when you play real games."
He continued: “They are a very good team and they have already played five games.
“That is one of the most important things in football, when you have already played games, you are fitter and you are better. But we have no excuses. We are Man United, we shouldn't lose and we want to win every game. But, this pre-season, we want to put minutes in our legs and I think we can be satisfied but, of course, Man United never wants to lose.
“When you have played five games you can say that you arrive one second before the opponent. It is a very important thing, but we don't want to make excuses. They are a very good team, they played fantastically and we missed some chances. But I have said before, they just arrived one second earlier. But I think we are improving, we are building a fantastic team and we are optimistic, of course."
