Manchester United captain Bruno Fernandes said the "same mistakes" were responsible for his side's shock 2-0 defeat to newly-promoted Hull City in their opening game of the Premier League season on Saturday.
First-half goals from Semi Ajayi and Nobel Mendy were enough to give Hull their first league win over United for 52 years.
"Same mistakes as we did last season, every away game," he told TNT Sports when asked what happened in Saturday's game.
"We give too much of the ball to them. I think they have, in the beginning of the game -- first 20 minutes -- the [Hull] goalkeeper was the one who had more touches on the ball.
"Too much time -- I think we need to press a little bit more, we need to be a little bit more aggressive."
Last season, United won 13 of their 19 home games in the league but just seven of their away games, drawing eight and losing four.
Fernandes also lamented the fact that both of the goals scored by Sergej Jakirovic's side came from set-pieces, with Ajayi touching home after Senne Lammens kept out Oli McBurnie's close-range effort, and Mendy heading in Regan Slater's free-kick to double the lead seven minutes before halftime.
"And then, again, set plays, we need to work on it, to be more aggressive and try to not concede these types of goals. Obviously, against teams like this, they're waiting for that moment," Fernandes said.
"Before the game, we knew that would be a big part of their game. They played a full preseason with a back four, they went against us with a back five, also to have some height for these moments, because they knew they could get a chance from it.
Obviously defending well our set pieces [is] what they did. The most frustrating thing is that we lost the game, that's it."
