But Ten Hag says they will enter the clash with confidence: "Our form. We are also in a good run.
"This period is very good, we are united. We are in togetherness and (we will) make a good gameplan. We have done it before against City and also, lately, against Liverpool, so we will prepare well.
"The players are ready for it and looking forward to it. I can smell it. I am around here and speak with the players, so we are really enjoying (it) and looking forward and excited."
Asked about previous derbies, Ten Hag said: "We did it in several ways, many ways, to be successful.
"So, from all the games, we look back. We had the opportunity to win one time and you need a great day.
"That is also what we know so the players have to give the best performances."
