Bologna surprised RCD Mallorca on their own turf with Marko Arnautovic and Riccardo Orsolini on target in a friendly victory.
Serie A is on a break for the 2022 World Cup in Qatar and will resume from January 4.
The Rossoblu were in Spain for this test match and came up against some familiar faces, such as former Lazio striker Vedat Muriqi and ex-Fiorentina defender Matija Nastasic.
Arnautovic opened the scoring with a left-foot scorcher from outside the penalty area, cancelled out by Kadewere’s header on a corner.
Orsolini sealed the victory just five minutes later from nine yards after a great run and cut inside from Musa Barrow, whose pass was let through by the Lewis Ferguson dummy.
