Manchester City, last season's UEFA Champions League runners-up, crushed RB Leipzig 6-3 in a thrilling Group A game at home on Wednesday as Christopher Nkunku scored a hat-trick for the German side. Nkunku became only the fourth player to score a Champions League treble and end up on the losing side and he deserved his player of the match award as Leipzig showed real spirit to keep fighting back against City's impressive firepower.
