Brescia coach Eugenio Corini was left frustrated after their 2-1 defeat to Juventus.
Alfredo Donnarumma put the hosts in front, but an own goal and Miralem Pjanic's volley earned Juve the points.
Mario Balotelli made his debut after the four-match ban left over from Ligue 1 finally expired.
Corini said, “Mario arrived with the right motivation, he is working hard and is an extraordinary player, so I am sure he'll give us a big hand this season.
“Being at home, close to his Mother, family and friends is helping him to focus on his life more. He seems very relaxed, fully involved in the team and I try to motivate him daily to give him more, as his abilities are unlimited. I realise I'm a pain for him, but I keep pushing him because I can't be content with just a fine performance."
On Sandro Tonali, he added: “He has technique, quality, physicality and the mentality of a great player. Sandro is extraordinary and it's remarkable to see the way he handles all this pressure, has the desire to push himself beyond his boundaries.
“He's got the DNA of a great player and he can help Brescia stay in Serie A while we help him become a great player."
