"I'm sure I'll get it done, I did it everywhere," said the man with no hesitation.
The new Manchester United manager was responding to a question on how long he needs to bring the glory days back to Old United and his answer had a lot of similarities to the one he gave in his first press conference after being appointed.
"If I stay here for four years, I am pretty confident that we will have a title," the German said.
It wasn't until 12 months after he took over that he was correct about the side's position in the premier league.
Will Ten Hag, who won three Eredivisie titles, including two league and cup doubles, be given the same amount of time at United?

When we sat down to discuss his team's start to the new season, he said that he couldn't ask the fans to be patient because they want to see a winning team. The process is what it is.
This is five days after United laboured to a 2-1 home defeat to Brighton - the Seagulls' first ever victory at Old United - to kick off the Ten Hag reign.
The source of the goal that gave United hope of a comeback and his side's response to going 2-0 down in the first half were positives for the new man.
He said that they made a goal out of set plays because they weren't that good in set plays.
I cannot ask the fans to be patient - I hope they will be - because they want to see a winning team and that is why I am here, but I have to produce it
There was a lot of concern for Ten Hag.
He said that a lot of the display was incorrect. The performance was not good and the result was not great. It is normal in the beginning of the season when you have to get together and play together.
We went well in the pre-season, but now we have to perform better because we don't have two of our best players.
However, Ten Hag insisted that his new charges were not suffering from a lack of confidence, rather it was individual errors that cost them dear.

He said that they were confident in preseason, good pressing and decisions, but that was not the case in the first half against the Seagulls.
At the beginning of the season, you have to be mentally strong.
Ten Hag will be hoping that the sloppy first-half showing at Old United was a one-off as he prepares to bring his team down to the capital for his first away trip as United manager.
He is aware of the challenge that awaits him and his players in west London on Saturday night against a side who scored three times againstLiverpool and only narrowly lost to title winners Manchester City.

"They are a physical, strong team, well organised, play direct, so we will have to be good," said the United manager as he looked at the Saturday Night Football clash at Brentford, one in which Anthony Martial will not feature due to injury.
While we may see a change in personnel on Saturday, there could also be a change in formation as Ten Hag ponders starting the game as he began the second half, with Christian Eriksen in a deeper-lying role as opposed to a false No 9.
He said that Christian is a player who can impact on different areas of the game. He can play more deep, but also high, and he can have a good impact.

Regardless of his lineup or formation at the Gtech Community Stadium, Ten Hag expects United to improve as the players begin to understand exactly how he wants them to play.
It is a big challenge and we knew that before. It takes time, but in football you do not have time and that is what makes it such a big challenge
"They know their jobs, but top-level sport is a fast game, we need to make quick decisions and they have to be connected," he said.
Would more players be brought in before the transfer window closes?
"We definitely need more players to get into the season, that is clear, we need a stronger squad in the middle and offensive departments," said Ten Hag.
We didn't have a good replacement when Martial was out and then we struggled. When you have injuries and games every three days and players are not recovered to play the next game, it's important that you have squad depth.

"In the short term, we have to win every game and get into the season and go," said Ten Hag, who would not be drawn on what constituted success for United.
The size of the task facing him and his staff was acknowledged by the former head coach.
He said that the challenge was a big one. Football is a big challenge because you don't have time to do it.
10 years ago, when United last won the league, success goes quickly, but you need a lot of work, a good strategy, the right people and that is what we are working for.
It is going to start on Saturday night.
