The Blues ran out 2-0 winners over local rivals West Brom at St Andrew's, and Hannibal opened the scoring with a cheeky free-kick, catching Albion keeper David Button out as his superbly taken effort curled into the net.
The 20-year-old, on a season-long loan at the Championship club, then turned provider with seven minutes gone in the second half, as his inswinging corner delivery was cleverly met by Polish midfielder Krystian Bielik, who nodded home to double the lead.
Praising a superb atmosphere on a night to remember for himself the West Midlands, Hannibal's delight was clear, as he spoke to Sky Sports post-match.
