Manchester United boss Erik ten Hag is demanding a stronger mentality from his players after victory Brentford.
Ten Hag concedes his players are still failing to take charge in games.
He explained: "I think we controlled the game without creating many chances and we had to get more box entries, but I think when the game is in the opponent's half, we controlled their counters - and they are quick, they are good on counter-attacks, we didn't allow them counter-attacks.
"They have got some standards, some set-plays, they are very strong in it and they had two opportunities from it but we didn't allow them one shot and we had some opportunities.
"And then, same story again, we concede a goal on a decisive moment, totally the wrong decision. Two or three players.
"We start without a formation and an easy giveaway and it sums up a little bit our season, with easy giveaways you get punished in top football. We have two good players to act like this.
"So this has to be a turning point but this also has to be a restart because we have to get into higher levels. The spirit is good, the belief is good, when the team is together, we have shown strong character and it can be the turning point in the season but it is up to us.
"When you can't handle the pressure, don't play here. Those players, they are so experienced. They are so high-quality players. They have to take responsibility.
"So I don't point to one player but I see it in the summer and the start to the season. We have to take responsibility. So defending, also on the ball, you have to take responsibility.
"In decisive moments, we have to recognise we need leadership to have a good organisation and we don't always have. We have a free-kick and we're out of formation but we start the play.
"From there on, it is easy, avoidable mistakes and it has to be out of our game if we want to be successful. But the good point is this team spirit, this team has strong character and shows belief, togetherness, in togetherness with the fans, I am sure we have to fight every season into the season and it can be helpful and a foundation to build on."
