Rob Valentino questioned Atlanta United's mentality after their recent drop in form and hopes to find a solution before meeting the New York Red Bulls in MLS.

The Five Stripes are winless in their last four matches, drawing three in a row before falling to a disappointing 2-1 loss to CF Montreal in midweek.

Sitting 12th in the Eastern Conference, they can still mathematically clinch a playoff spot, but they have to win their final two matches and hope other results go their way.

Valentino was not happy with what he saw from his players against Montreal though, questioning their desire.

"We should always be fighting to win the game, and you just can't give up," Valentino said.

"I'm not going to sugarcoat things, but at the end of the day, I also see that it looks like it doesn't really matter [to the players]. It should look different.

"It's about recovering and going again, but there's no easy solve."
