Whatever happens dont think that Juve gets much worse without CR7.
He was signed to give the team/club a confidence boost to win in europe and that didn't happen.
But when it comes to Serie A they never needed him nor do they need him now. Especially under Allegri whether they win or not will depend on the time needed to adapt to allegri mentality ( winning 1-0 > 3-2) .
All they need to do is tighten down defensively and not do fuck ups like last match from 2-0 to 2-2. But as for scoring potential is always there with dybala , chiesa and the rest plus whomever they sign.
