Yes and in an interview Ivan Juric stated as if he had worked very well and did not accept when there was lot of bad talk about AS Roma performance and defeat against team that actually had much lower level than them, but this is ridiculous because defeat is still defeat and of course there will be lot of negative sentiment so they have to be able to accept it.
But indeed in that match, statistics show how Roma's dominance and many attacks were much greater than their opponents. However, all of that was in vain because it was ineffective and there were no goals at all, IF Elfsborg was indeed quite lucky because they got a penalty kick opportunity, and Roma was very unlucky with that. But behind all that, the point is that Roma's game at that time was not optimal and still wasted many opportunities. We'll see in the next matches, how they develop under Ivan Juric. In Serie A, Roma did get a win in their last match.
Ten Hag has not only messed up the team, but he has spent a lot of budget to recruit new players, but so far all his efforts have not been able to provide the expected impact.
I found a very interesting illustration about Ten Hag, Man United, in their last match against Porto.
