Thanks to his 18-year-old body, Tang Long's injury recovery was faster than the team doctors expected.
Three days later, the rib bruise was barely visible, and he practiced with the whole team for 20 minutes that day.
After Mancini and head doctor Siris exchanged views, considering the importance of the upcoming match, he decided to include Tang Long in the substitute list and take him to Lazio.
Chiwo, the first-team coach, thought Mancini was too conservative about this arrangement.
"Boss, why not start Tang? He's only 18, this little injury is nothing at all. Against Lazio, a direct rival for the Champions League qualification, we need Tang's midfield coordination and command!"
Mancini replied: "Tang hasn't had systematic training for three days, his physical condition is still unknown, and he hasn't participated in the coach group's targeted training for Lazio. He still needs observation, and if the situation allows, I'll give him 20 minutes."
