Manchester United have dropped five points from winning positions in their last two games, with the most recent missed opportunity coming against Chelsea at Stamford Bridge on Thursday.
Cole Palmer scored twice deep in second half added-time as the Blues stole all three points in a dramatic 4-3 victory over Ten Hag’s outfit.
Mason Mount thought he had found the winner with his strike in the sixth minute of stoppage time against Brentford, but Kristoffer Ajer equalised three minutes later in a 1-1 draw last Saturday at the Gtech Community Stadium.
Ten Hag admitted his side need to start getting over the line when leading games, seeking inspiration from previous victories over the league’s best.
“We can play to a very high standard. We can compete with the best and beat the best in the Premier League and when you can do that, you can also do it across Europe,” he said.
“We need to learn how to bring big games over the line, Saturday was an example.
“We have to step up, make better decisions individually and as a team.”
Thursday’s defeat in west London ended an unbeaten Premier League run against Chelsea which started in 2017.
Ten Hag wants his players to use the defeat as fuel going into their clash against Jurgen Klopp’s Liverpool.
He added: “We will see on Sunday (how to beat Liverpool).
“But I have to say first I have to deal with this, but we can’t deal with this long. We have to recover very quick. We have to turn this around.
“We will be in a positive mood. We will be looking forward. We have to take energy but we will be mad, angry. From anger you can take a lot of energy and that is how we have to do it.”
Marcus Rashford came off the bench at Stamford Bridge, but failed to have an impact on the night.
Ten Hag revealed the forward is as motivated as ever to help the team.
He said: “I think lately his form is progressing and so the time will always be right. I think he has a big motivation because he wants to be successful with us.
“He wants to score goals, but he wants to win trophies and contribute and we still have a chance in the FA Cup.
“He wants to fight for a Champions League spot and the Euros are coming so I will say his motivation should be high.
“And the form, that is a moment and he can change the momentum always. Before Brentford, he scored three goals in three games.”
