The Manchester United boss admits he is impatient but accepts it will take time to develop the team.
Ten Hag took charge of United in the summer and has overseen steady progress with the team winning their last seven games in all of the competition.
Sky Sports will show United's game against West Ham at Old United on Sunday.
The side has scored 16 goals in the league this season, which is the lowest of the current top eight, but the coach has called for patience.
He said it took time to develop a team. It's not possible to go from zero to 100 in a single day.

"Unfortunately it takes time and I don't have time and I'm really impatient but I have to wait so it's clear."
The players are more aware of the need to defend with 11.
"Also, our build-up is improving game-to-game so now we have to develop more on our attacking game but it's the most difficult part, so it takes even more time." I want it, but we have to wait.
United's last loss came at the start of the month as they were hammered 6-3 at rivals Manchester City, but Ten Hag believes the loss has provided them with good lessons.

After the international break, we forgot our rules, principles and beliefs.
It's like a pack of cards when you play against City and one player makes a mistake, you get good lessons for the weeks after.
You don't want to go through that. We have learned a lot from facing opponents of Man City.
Anthony Martial is still recovering from a back injury and will not be in the squad for the game against West Ham.
He is still waiting to return to the first team but is back in training.
Ten Hag said he hopes Martial plays before the World Cup. We are waiting for his step back in team training because he is working outside so he is on the pitch.
He had a problem as he fell out. It's frustrating for us but also for him, he's had some injuries.
It would be great to have him back because he can make a difference and he has scored three goals so far this season.

In preparation for Sunday's match against West Ham, United beat Sheriff Tiraspol with three goals in a row.
After the summer signing Antony put the ball out of play in the first half, it was one of the main talking points of the game.
"If it's functional, I don't have a problem with that," said Ten Hag, who took the Brazil player off at the half-time break.

More runs behind, more often in the box, more followers in and more tempo dribbles are what I want from him.
It's nice when there is a trick like that.
If it's functional and you're not losing the ball, then it's fine.
I will correct him if it is a trick.

Needless skills were a thing of the past forRonaldo when he first arrived at Old Manchester.
After refusing to come on against Spurs last week, the 37-year-old returned to the starting line-up on Thursday night.
The 701st club goal was scored byRonaldo, who was having a hard time in front of the goal.
The team kept putting him in the right position because he kept going. He was going to get himself in the right place.
He never gave up. His entire career is about that. He is so good because of that. He got the reward for it.
One of the all-time greats was in action on Thursday, but also a rising star.
Alejandro Garnacho received a standing ovation after making his first United start at the age of 18.
Ten Hag thought it was a good performance from him. I expected him to do what he did.
He deserved the chance after a while.
He got a better attitude, more resilience, more determination, and what you see he is a talent, I was not happy with him, but the last weeks I was happy with him, he got a better attitude, more resilience, more determination, and what you see he is a talent
"To deal with the ball in tight areas, to run behind, and especially histempo dribbles, he can take players on and that's a good capability in football nowadays, especially against opponents who are defending that compact."

I'm pleased with that. I hope that he knows that he has to do better to get into the team and that he doesn't forget the other things. You are in a group of people.
Pushed on what Garnacho had done wrong. It's young children.
They have to know what is expected of them in top football and they have to grow up.
It isn't just about a trick or a goal. We have to win football games in order to fulfill the highest standards.
We have to teach that to him and all the players.
