Two goals and a man down, with Adrien Rabiot having been sent off, Ronaldo managed to strike twice to earn the point.
Pirlo said, “We have midfielders suited to a two-man system, so Bentancur, Arthur and Rabiot all have these characteristics and we have to put them in the condition to give their best.
“Unfortunately, these are all situations you can't test out in training, it needs to be a match. Arthur needs time to adapt to Serie A and to our style of football, not to mention he's not fully fit after so long out of action," continued Pirlo.
“Bentancur played if anything too much last season, he ended the campaign exhausted and has been doing specific training work to get back into shape.
“We're very glad to have Ronaldo, as he doesn't just provide goals. He ran more when we went down to 10 men and that was a great help to his teammates."
