Postecoglou acknowledged that his team was affected by the changes, but praised their endeavour and effort. He said that they worked hard in the first half, but ultimately couldn't control the game. He noted that the second goal scored by Arsenal straight after halftime killed the game.

Postecoglou has six games in all competitions before the next international break, which he sees as an opportunity to start bedding down his team's principles in terms of how they want to play. He emphasized that he wants to see changes in Forest's play as soon as possible, and is determined to get his team to where he wants them to be quickly.

In fact, Postecoglou is aiming for his team to start showing his preferred style of play as early as this week's League Cup game against Swansea City. He believes that it won't take long for his team to adapt to his approach, and is committed to getting them to where he wants them to be as quickly as possible.

Postecoglou was appointed as Forest's new manager on Tuesday, giving him little time to work with the players before the game against Arsenal. His teams are known for playing attacking football, but Forest's performance against Arsenal was flat.

Postecoglou is confident that his team will start to play to his strengths soon, and is excited to see the impact of his approach. He believes that his team has the potential to be stronger this year, and is committed to getting them to where they need to be.
