he showed pretty steady progress until the covid break, and started to make those stupid mistakes once the calendar got too busy with matches every 3 days. some other players like bonucci, pjanic, matuidi or higuain (etc) equally turned to complete shit during that period.
bottom line is that bentancur is a better player than he looks now. same goes for de ligt, rabiot, dybala, ronaldo, tek, and the majority of our squad. chiesa and cuadrado are those two players who have an excellent season, morata was great until that virus hit him. the others are certainly underperforming, including bentancur. we can sell him, especially in a tricky package deal if we find a club that's willing to screw with boca, but i don't think it will happen. he stays, so let's hope he rediscovers his better form.
