He wasn't this bad in his earlier phase of Inter career. Actually he was very good back then. He was useful offensively at least. His defensive game was always a huge let down, but at least he managed to back it up with offensive contributions like assisting and scoring, also he was a far post threat since he managed to win quite a few headers. But now looksl like he can't get to execute anything properly.
When situation like this happens, even these players with great character can be affected, let alone these whom are fragile mentally. It's all on Limone and his incapability of coaching a top club. I'm not here to excuse his pathetic performances, but the guy is not as bad as he seems these days. Besides of that, we have even our top players like Barella, Lautaro, Bastoni and the rest whom are struggling like hell.
This club needs to reflect quickly on this situation because we are in a serious risk of missing out on CL football for next season.
