Simone Inzaghi is having a perfect performance in Inter Milan and this made the fans happy so far. Also, Inter Milan wants to have in this coach on the team for a long time because of the performance they have seen so far from Simone Inzaghi in both Serie A and the Champions League, Inter Milan is aiming for both the title of Champions League and the Serie A title.
I won't say Simone Inzaghi has a perfect career with Inter Milan because he can't win UCL yet. However, he surely experienced great career, he already won some domestic trophies with Inter Milan. So far, Simone Inzaghi won 6 trophies with Inter Milan. 1 Serie A trophy, 2 Italian Cup trophies, and 3 Italian Super Cup trophies. It is quite impressive, he always won trophy in each season.

Maybe they should find another coach to fill the place of Ten Hag in this team.
Well, he has a contract with Inter Milan until June 30, 2027. It means he will stay in Inter Milan for the next 3 years. Since he looks happy with Inter Milan, I don't see a chance that he will consider to leave Inter Milan. He is also an Italian coach, he should feel more comfortable to stay in Italian league (Serie A). Moreover, all his career history as a manager is in Italia, this is also this first time that he manages one of the top team in Italia (Inter Milan). I personally think that he will obey his contract. Even he wants to move to another league, it seems it will happen after his contract with Inter Milan is over in 2027. So, it is unlikely he will manage Man United. It is also not a better team than Inter Milan. Inter Milan is much a better team if we compare with Man United.
