Ten Hag said: "The process is not going as we expected. That's the truth. The setback, if you want to call it like this, we want also to do it very careful. When he is now dropping again, we want to be very careful. We know his past, we have to do this right, because we want him to be available, because he will have a big impact on our performances and also on our levels. We can't have him playing for some games and then drop out again. So, we will do it very carefully."
