In his first game in charge, Tudor saw his new team hammered 4-1 at home on Sunday.
Asked for his first impressions, the Croatian said: "Big gap in this specific moment between the two teams. It was too much Arsenal for us in this moment with the problems we have. Also it’s nice to understand where we are because you prepare in the best possible way then there is the game to show you reality.
"So it’s nice from one point of view so each of us understand and come, as I said the players, stay quiet they come on Tuesday and restart after these three or four training sessions to start to work harder than we did until now. To change our habits, to change the state of mind which is now as a team. It is the only way to work."
Tudor also stated: "Too much problems in this moment to let this level of team not punish you. Because you wanted to go to press high but to press high from back you need to jump so if you are late and don’t take the ball around there, also with the ball. So we prepare to press high but we didn’t take the ball. So we need more time to be in a physical moment and physical situation that we can go strong and take the ball. Now we are not in that moment.
"Even with the ball, a lack of confidence is very evident in the team. So we wanted and prepared to do the things but there is an opponent, there is a reality today. So I’m very sad and very angry and everything but in one way it is also good to understand where is our goal. What is the goal of this club.
"What is the goal of this team. What is this goal of this coach, these players, this staff. To become serious. Serious, not just a group of 20 players, and the medicine is you look in the mirror. Each of us look in the mirror and really try, really start to change the habits. Working hard is the only way."
