Ange Postecoglou has admitted his position will be under “a lot of scrutiny” if he has not lifted Tottenham out of mid-table by Christmas. The club play at Manchester City on Saturday – the start of what Postecoglou called a “pivotal” nine-game sequence in 29 days – and he was keen to highlight the fine margins at work.

If Spurs had beaten Ipswich at home on the Sunday before last, they would sit third in the Premier League. They have the second-best goal difference in the division, are into the Carabao Cup quarter-final – where they have a home tie against Manchester United – and are going well in the Europa League.

Instead, they were beaten by Ipswich – they have lost before each of the three international breaks – to lag in 10th. Postecoglou made a fast start to his Spurs tenure, winning eight and drawing two of 10 league matches at the beginning of last season. Since then his record in the competition reads W17 D5 L17.

“It’s a significant period and at the end of it we could be in a decent position for a strong second half of the year,” Postecoglou said. “You can build some momentum or if things don’t go well you could get yourself into a bit of a grind. So it’s going to be a really pivotal part of the season. If we’re still 10th then people won’t be happy, I won’t be happy. But we might not be 10th.

“If we had beaten Ipswich, we’d be third and I reckon this press conference would be much different. I’m not going to let my life be dictated by one result. I take a wider perspective because I know how fickle it can be. But we need to address our position. And if we’re 10th at Christmas it won’t be great – for sure. Rightly so, there’d be a lot of scrutiny and probably a lot of scrutiny around me. That’s not where I plan for us to be.”

Postecoglou, preparing for his 50th league game in charge, said Spurs were “definitely a better side than we were last year”. He also remembered where the club were when he took over. They had finished eighth, failing to qualify for Europe, and were about to embark on a squad overhaul in terms of personnel and style.

“I think there’s enough there that shows we are progressing and developing into the team we want,” Postecoglou said. “The key is the next 50 games: if they can be, in totality, better than the first 50? First, that means I’m here. Second, I think we’ll be in a good space. I firmly believe we’re on the right path. I firmly believe in this squad of players. I firmly believe we will have success. But I can see why outwardly, if you put a pin in it right now, it doesn’t look that way.”

Postecoglou reported that Cristian Romero would miss the City game as he looks to recover full fitness after hamstring and toe problems. The manager’s other first-choice centre-half, Micky van de Ven, is out with a hamstring injury, meaning Radu Dragusin and Ben Davies are likely to start.

Romero came off at half-time for Argentina against Paraguay on Thursday of last week and missed his country’s game against Peru on Wednesday. His daughter, Lucy, was born on Tuesday. Postecoglou admitted Romero had not been properly fit for a few weeks and he was asked whether he might have had second thoughts about him travelling to South America.

“Yeah, you do,” Postecoglou replied. “But there’s always a line there, especially with someone like Romero, where you’ve got to trust his judgment as well. He understands the responsibility he has.

“I think when he went away, he realised that this is not healing the way we want it to. I said: ‘Just have a break. We need you 100% fit.’ As much as we’d love to have him out there, it’s best for him he gets totally over everything. He had the birth of his daughter this week, which is a significant event in his life. It’s important for him to pause a little bit and just spend some time with his family. He’s kind of over both [injuries] now. But we’ll just wait.”

Postecoglou also addressed the fallout from Rodrigo Bentancur’s seven-game ban for making a racial slur against his teammate Son Heung- min. The club are understood to have not fined him and want the FA’s suspension reduced to the minimum tariff of six matches but their appeal has been criticised for its bad optics, particularly as their position is that Bentancur has made a mistake. The seventh game of his ban is against Liverpool.

“I couldn’t care less who it is against and, yes, the appeal is worth it,” Postecoglou said. “We still have a judicial process. That’s why appeals are there. We think it was harsh, we think it should have been the minimum [punishment] and we’ll go through that process.”
