Hmm. Mario Balotelli in my old save didn't have much luck. In Inter he was deemed surplus to requirements and IIRC on the 2012-13 season (after few appearances and goals) he moved to Roma for some 17.75 million pounds, where he was mostly benched for further three seasons, then moved to Juventus for that same 17.75 million pounds, and yet again he was frequently benched. It went on until 2018-19 season, and then I stopped playing there. Who knows how Balotelli will be if I continue playing.
Also on that save, R. Madrid tends to have a habit of spending big bucks on backup goalies. IIRC they spent somewhere between 15-20 millions pounds for Fernando Muslera (Lazio), who would spend four seasons in Madrid and play only 2-3 league games in that period of time.
