Manchester United coach, Erik ten Hag cannot believe his team failed to win at Stamford Bridge despite being in a good position to collect all three points.
United found themselves falling two goals down, with goals from Conor Gallagher and a penalty by Palmer. But United turned the table around leading 3-2 after a brace by Alejandro Garnacho and Brono Fernandez.

Palmer dispatched the 100th-minute spot-kick before netting a deflected effort a minute later to snatch all three points for Chelsea and complete his hat-trick.
“Yes we started poor, kicking the ball away and defending poorly,” ten Hag told TNT Sports.
“But you saw we were dominating the game and it was brilliant how we played – we deserved to win the game.
“But, you cannot give it away like we did and we have to manage this game better.
“It is a team performance, you can point to one of the players but it is about team performance.
“When it gets chaotic you have to deal with it as a team and we made the wrong decisions and we didn’t help out as a team.
“Out of possession we made bad decision – a lack of concentration.
“Also, I think lucky at the end with the penalty situation, questionable and very soft but we have to do better.”
Ten Hag added: “Definitely a setback and now we have to deal with this and get up – we are resilient and you have seen that today.
“Manchester United dominated the game but we made individual errors that cost us the game.”
“In five days we dropped five points. That is unacceptable. We should have a high standard if we want to compete for Champions League football.
Manchester United captain Bruno Fernandes also admitted that his side threw away a good result on the road.
He told TNT Sports: “We had the game in our hands and we gave it away.
“It’s frustrating. It’s difficult to take. We had good control in the last few minutes. But they got two chances and scored two goals.
“From the corner we have to be much quicker. We knew beforehand they take corners and throw-ins quickly.
“In the last games we’ve conceded too many shots. It’s about defending your box.”
