Started a learning career with AS Monaco, within three years got them winning the Europa League and then the champions league in 5. It helps that they're extremely wealthy, but unfortunately not very initially popular. Nor do they have a very large stadium, but I got them to build another. I lucked out though, as both an underperforming Chelsea and PSG did a firesale of their best players, many of which they rather weirdly sold to me. Thus, I ended up with a pretty killer lineup which included Oscar, Lucas Ocampos, Yannick Ferreira Carrasco, Lucas Romero, Hervin Ongenda, and even Courtois (Chelsea actually sold Courtois WTF). Needless to say, the other teams in the league could only watch in horror as we went on routine 8-month long unbeaten runs, adding 5 coupe de la ligues, 4 Ligue Ones, 4 coupe de frances, 1 EL, and 2 back to back CL to our already large collection. It's a nice feeling going to clubs like Manchester City and PSG being favorites to win.
After hammering Arsenal 8-0 on aggregate and spanking Real Madrid in the 2018 CL final 5-1, I decided it was time to leave Monaco the next season, but not before hooking the fans up with a new stadium and building state of the art youth facilities. Unbeknownst to the ai, I had been buying up the worlds most promising young talent (mostly regens w. insane potential, gamey I know), so even without me the club would be set for generations with french and Argentine talent. Then, halfway through the next season, I received a call from FC Bayern Munchen president Karl Heinz Rummenige. Bayern, who had succession of poor managers, were languishing in 6th in the Bundesliga and were without the services of Robben, Ribery, Alaba, Muller, and Benatia. Not much of challenge restoring a club like that to dominance. Still, I like to make career choices that I would make in real life.
On the international front, I got my first gig w. the Ivory Coast, inheriting an aging squad that was still good enough to compete in Europe. My first trophy with them was the African Cup of nations. After crashing out of the confed cup in the group stage I somehow got the boys to a WC semifinal and 3rd place (after a heart attack inducing 5-4 goalfest w. Spain, plus Bonny and Drogba make a killer duo). Knowing that the squad would likely never repeat that sort of success again, I jumped ship to Argentina, where I introdued enough young talent to win 2 Copa Americas and almost win a Confed Cup. After getting edged by an OP France in the next WC, I gave up International management for a week or so, only to switch to the Netherlands as son as the job became available to try and rebuild them.
TL;DR: Started at AS Monaco, made them like Real Madrid. Moved to Bayern to trophy-hoard.
