Jesse Marsch is in no doubt results will turn around, but the New York Red Bulls coach has called for patience.
The Red Bulls - third in the Eastern Conference - open the MLS round at Houston Dynamo on Friday, having failed to win their last three fixtures.
Marsch and Co. conceded two goals in the second half as they lost 2-1 against Seattle Sounders last week, following on from a 2-0 loss to Philadelphia Union and a goalless draw with FC Dallas.
The Red Bulls' winless streak comes after they lost only one of their first nine games but Marsch is keeping the faith in his tactics.
"I understand why people have questions about different things," Marsch said ahead of their trip to Houston, who are eighth in the Western Conference. "That's what happens when you don't get results that you need and should be getting.
"If we were playing in games where we were outmatched, where we were outplayed, then I think there would be more cause for concern about where we're at with different things.
"I've tried to say from the beginning that this is a process. We've changed a lot of things, but that doesn't mean that all of sudden, overnight, there's going to be success."
