I really hope he stays at AS Roma I like Jose's way of doing and in any case thanks to him AS Roma reached the Europa League final two years in a row, I consider it a good result
It is not easy to convince Mou to stay in Roma, the best way to do that for a coach like Mou is to give him an open check to sign any players of his choice but me and you knows too well that Roma cannot take that step so it is expected that Mourinho will leave unless Roma brings in more quality players for him to increase his team depth.
For me I will love Jose Mou to leave Roma and continue his adventure in another team. I love to seem him in different teams and different countries adding spices to different leagues.
Roma is not rich enough to give him an open check to sign any player he wants. I mean by that logic, even though it is unrealistic, we could give example of "him spending 300 million to get Mbappe", would that happen? Of course not, and even if he was given open check he knows it is not that open. But even within their budget, if he spends it on just a single player then they would argue against that.
If you tell someone they have 50 million euro to spend all summer long and they buy one player on day 1 so that he could just continue and reroll again with just one different player, then you would be against it as well. This is why they can't afford to just give him an open check, everything must go through the management without a doubt.
