Harry said that retaining the captaincy has given him a lot of confidence and that he has brought energy and positive vibes to the team.
Since taking over at United at the end of last season, Ten Hag has enjoyed an impressive start to his career, with the highlight being the team's pre-season victory over the Reds.
The Dutchman is preparing for his first competitive test against the Seagulls in the premier league on Sunday, live on Sky Sports, and he believes United are in the right shape to hit the ground running

The work of Ten Hag has been clear during his time at United.
It was obvious during the summer that the tenets Ten Hag had been teaching his players - sharper reaction, surety in transition, confidence on the ball and lack of it - had been taken on board.
When United recorded their lowest points tally in the premier league era in the last campaign, the fans deserve better according to the 52 year old.
The club is all about winning. We need to look at huge improvement from where we were last year.
For this club, last year was not acceptable. We did not give our fans anything to look forward to.

We have to make sure we're in the major tournaments for large parts of the season and come March, we're still playing in them.
The club is not used to playing Saturday, Saturday, Saturday in the last few months of the season.
We didn't do well in the league and were out of cups. We need to improve our performances and give our fans something to be excited about.
Excuses can be found in everyday life, and we need to look at ourselves. We didn't perform well enough and the team didn't perform well enough as a group.
Some even suggested that he should be stripped of the captaincy as a result of the United's disappointing campaign.
According to a study conducted by the Alan Turing Institute in association with Ofcom, the only player in the premier league who has received more abuse than him on social media is CR7
Ten Hag has not allowed outside noise to affect his judgement and has shown his support for Maguire, guaranteeing he will keep the captain's position.
"That's three managers now I've captained the club under, it gives me a lot of confidence and trust in what he sees in me around the place and around the dressing room."
It is an honor to be the captain. I'm used to it and I'm big enough to take what comes with it. I'm excited to lead the team again.
He said that he never thought about not wanting to be the captain. It's a huge privilege to play for this club, but to be captain and lead the boys out at Old Manchester is an amazing feeling.
There have been many ups and downs in my career. I'm at a point in my life where I'm an experienced player.
I have played for my country and in the premier league. I think I can take the criticism that comes with it.
Everyone at this club has been in the past and they like to be talked about in a positive way.
In the first two years at the club, we were on the right path. Last year was a big blow for me as well as for the club. We need to make sure we keep going.

Despite retaining the captaincy, Maguire is having to adapt to a slightly different position.
A switch to the right is not an issue for the Argentine, who plays as a left-sided centre-back.
He was happy to have him in. I started on the right and moved to the left towards the end of my career. I don't like anything.
I have played for England and a lot of other countries. I look for someone who can help the team and be involved.
He is in the building. Bring as many people as you can to help us compete for the major trophies.
I want this club to be successful and win some silverware. We will be able to do that if we have more competition.

The impact of the United team-mates has become the subject of intense speculation recently.
In a pre-season game against Rayo Vallecano last weekend,Ronaldo played for 45 minutes but told the club that he wanted to leave to play in the European Championship.
Since the return of the five-time Ballon d'Or winner to Old United, what has he brought to the team? He is a great player and a great person.
He takes most of the speculation and I know what it's like to have a lot of it. He does a lot of things that are scrutinized a lot.
The size of the club is what you get when you play for it. When things are going well you get a lot of praise.
