Ange Postecoglou believes he has been backed in the transfer window ahead of the market closing later today.
Spurs are not expected to sign anyone else this window, but they have already brought in Dominic Solanke, Archie Gray, Wilson Odobert and Lucas Bergvall.
Postecoglou, who turned 59 this week, is happy with how the squad has been shaped this window, with the age demographic of the squad continually lowering.
"If nothing else happens — a couple will still be moving out — I think it's been another positive window for us. [Each window] you want to come out of it in a stronger sense. I certainly feel that," the Australian outlined.
"The players we brought in are making a short-term impact, but - even for the longer term - they will be really good contributors for us. We have a really well-rounded squad to deal with the extra games and whatever injuries we have. It's been a really pleasant window."
The former Celtic manager, who jokingly said he thinks will get a warm reception when Spurs travel to Rangers in the Europa League, continued that a lot of work has been done since he arrived.
"I'm very happy. I think we've done a lot of work in the last 12 months. No doubt the squad has changed — the demographic has changed and [for] the suitability of the style of football I want to play, we are certainly more adapted for that," he stated.
"We needed to do some fairly major work 12 months ago, but there's still work to be done. I don't think it should happen quickly. When it does happen quickly, I think you are more likely to get it wrong."
Postecoglou later added that he believes he has been backed, and that he always looks at the long-term plan when thinking about transfers.
"When you plan to rebuild a team, all managers hope they are here for the long term. But, the reality is that you do not know how long you will be there," the manager stated.
"I have always tried to build a team that will last over a cycle, which is three/four/five years. As a natural consequence of that, you are looking at a younger demographic — a team that will grow, improve and adapt to the challenges ahead.
"When I got here, it was a team that looked like it was at the end of the cycle. Players who had great careers but were ready to move on or getting to the end. That combination, with a different approach, was part of the plan to go younger."
Tottenham's poor record against Newcastle recently
Tottenham's last two trips to St James' Park have been journeys to forget. They lost 4-0 last season, whilst - a year prior - they were humiliated during a 6-1 defeat.
In both situations, they have crumbled under pressure, and the Australian has consistently talked about wanting his time to learn from previous experiences ahead of Sunday's match. In his pre-match press conference, he outlined what went wrong in the North-East in April.
"[There was] a bit of a contrast. Here at home, we did really well against them, but, up there, we didn't. It was a good learning curve for us. We started the game ok and then we conceded. We lost, our first time all year, our composure in the game and we allowed them to score quickly. We know what it's like up there," he said.
"The crowd created a brilliant atmosphere for their team and we did not handle it well. It was a good learning curve. We want to learn from that, but it's still a tough game any time you go up and play Newcastle.
"They have got some outstanding players in their team, they are well-coached and it's going to be a great challenge."
