It's funny how someone not wanting to follow only the money may be seen as lazy. Don't you think his staying at Juventus is the more difficult decision? Juventus is in a very bad situation right now and he doesn't want to bail out on them now that they need him most. He believes he can bring the club out of that situation and back to the ucl and win the league title. There's nothing wrong with having faith in yourself and the club you love and work for. I am not a fan of Allegri but he has done it at Juventus before and he can do it again if he has the support of the club and fans.
Let's not exaggerate Massimiliano Allegri's loyalty to Juventus too much. By Italian standards, the salary of the head coach is very good and amounts to 9 million euros, and I think that the current offer from Saudi clubs is not the last and Allegri can return to it when their paths with Juventus diverge. Also, do not forget that the penalty for breaking the contract, which is calculated until the summer of 2025, is even greater and amounts to 25 million euros according to some sources and even 36 million according to other sources, so this makes the Juventus management be more tolerant in case of Allegri's failures in terms of results and, accordingly, Allegri himself feels more protected from the whims of management and be more confident in your positions at the club.
