Manchester United are "better equipped" to win the Premier League this season but have to be "much, much better" to challenge for the Champions League, says manager Jose Mourinho.
United won the League Cup and Europa League and finished sixth in the league in Mourinho's first season in charge.
Asked if he was targeting the domestic title this season, he told BBC Sport: "We are better prepared for that."
United have signed Romelu Lukaku and Victor Lindelof so far this summer.
"This season is going to be more difficult but I think we have better conditions to fight for the Premier League," Mourinho told BBC Sport.
"I think this season we are a little bit better equipped. We are against fantastic teams, against amazing investments.
"But I believe in our group, in our spirit, in our empathy, in our togetherness. I trust my boys and we are going to try."
As Europa League holders, United qualified directly for the Champions League group stage.
"We went to the Europa League as one of the top teams, we go to the Champions League and we are not one of the top teams," Mourinho added.
"We have to be better, much better, for that objective. The base of everything is to find what I call a happy dressing room."
