Managers need to be able to adapt to the player material at hand. I know on paper it probably looked to ten Hag as if he would inherit a good team, but the problem is he got a team full of mid-table quality. Now he can either start adapting to this truth or keep trying to play like Ajax who were absolute top dog in their league, but I guarantee, if he keeps on doing that we are going to be still in relegation place come December.
There is another thing, ten Hag is very well capable of playing more defensive, counter-attacking orientated football. He did that perfectly fine with Utrecht against the big teams in the league. Ten Hag, and by your reactions a lot of our fans need to realize that we are not in a position of power anymore, we are a bog average mid-table PL team now and playing like big dogs will get us slaughtered many more times this season.
I would advocate for ten Hag to take a more conservative approach for now, make certain the recruitment team can get the right deals for a more progressive style over the next couple of years and slowly start to implement it. Against the lower table teams that only sit back, we can already practice this style, but against the other teams we need to be more pragmatic or ten Hag won't survive the season. And no stubbornness won't solve our problems, spot on transfers for players that fit the league and the style that ten Hag wants to play will.
