Bullshit. We went from 5th with one FA cup to getting 2 cups and qualifying for the CL during Mourinho's first season. In the second season we finished second comfortably and had a FA final. That is an improvement no matter how you look at it. The players Jose brought were generally good purchases - Zlatan, Lukaku, Alexis (granted he has not played as well as we would want, but he came basically for free which is a bargain), Fred and Dalot remain to be seen.
You talk about spending that kind of money, but is Mourinho the only one who spends money? Look at City, Liverpool, Chelsea. Are they not spending ridiculous amount of money, as well? Chelsea just brought a keeper for 70 million and Guardiola is buying players left and right with no care in the world.
Furthermore, I will repeat this shit again because some of you do not seem to get it. The squad Jose inherited was miles inferior to what Guardiola inherited. Let's be honest here. City had world class players in KDB, Silva, Aguero, Kompany and a decent-good player in Sterling. We had a world class player in De Gea and a decent-good player n Martial. When you compare the situations, it becomes crystal clear how miles better Guardiola had it compared to Mourinho and yet Guardiola has spent even more so than Mourinho. Yet people here are praising Guardiola like he is Jesus Christ and putting down Mourinho
