Teg Hag said: "We overperformed last year and this year, we are underperforming. We have to do better. We know the reasons why it is not working.
"No team can deal with so many issues and injuries we have had. We should still have done better and we have depth in the squad, but when you have so many injuries, the depth is not enough.
"They (the owners) know that when I have a squad available, the results will be there. I believe that (things will improve), especially when players return. Every time you swap (players), the routines are not there.
"We went for the win and it was one counter-attack where we didn't defend but what I saw in the second half was a team. It was good to see. I saw some decent football."
Nottingham Forest boss Nuno Espirito Santo has praised Bruno Fernandes as one of the best players in the Prem.
He said: “I have a big admiration for Bruno Fernandes - he’s a big player, a special player.
“I don’t want to say too much but he’s definitely one of the best players in the Premier League. He’s so competitive.
"Maybe some of the guys in the media criticise him but being competitive inside the game is something I think all professionals should have.
“It doesn’t mean you can ignore winning, drawing and losing. But it makes a big difference in your life and changes everything so to have this desire of always wanting to win and always wanting to do it makes you grow and makes you better.”
Erik ten Hag believes Rasmus Hojlund will start finding the back of the net more regularly after finally scoring in the Premier League.
The boss said: "I have to repeat myself, I trust him. I know his goals in the Champions League showed what he did as a young player in Denmark, in Austria, in Italy and he is a very strong character.
"But, of course, this goal will give him confidence and belief that he is going to score, and he is going to score more goals from this point on."
Erik ten Hag has revealed that Man Utd will maintain without several key players until mid-January.
The boss said: "I think in mid-January, we expect many players back, Mason [Mount], Casemiro, [Lisandro] Martinez, [Tyrell] Malacia. So, we expect Harry Maguire [back] of course.
Ipswich fans are in line to make a sensational transfer swoop for Manchester United winger Amad Diallo.
Diallo, 21, impressed while on loan at Sunderland in the Championship last year.
The winger scored 14 and assisted four times during his stay with the Black Cats.
Many expected him to play a role in the United squad this year but he suffered a serious knee injury during pre-season which has seen him only recently return to training.
That means he needs minutes in the legs and high-flying Ipswich are reportedly willing to offer him the chance to return to first-team football with a loan move.
The Mirror report that Ipswich are looking at Diallo after an injury to George Hirst and the end of Dane Scarlett's loan from Tottenham.
Southampton are also set to rival the Tractor Boys to the signing of Diallo with the club sitting third in the table, five points off Kieran McKenna's side.
