He has 1 more point than Pirlo had at the same stage of the season (28 pts V 27 pts, 15 league games played)
27 goals scored/14 against for Pirlo, 26 goals scored and 12 goals conceded for Motta.
Dreadful.
Actually, Motta is a lot worse.
First of all, yesterday we played round 16, and Motta's Juve has 28 points after 16 rounds, not 15.
Pirlo's Juve did indeed have 27 points after round 15, but that was also because round 3 (the match vs Napoli, which we won eventually) wasn't played until after New Year. In the opening 16 matches in Serie A (rounds 1-17, without round 3), Pirlo's Juve won 33 points (goal difference: 35:16)
So it's
Motta 28:33 Pirlo (points)
Motta 26:35 Pirlo (goals scored)
Motta 12:16 Pirlo (goals conceded)
Motta +14:+19 Pirlo (goal difference)
