This had been billed as being the bigger occasion for Palmeiras, whose noisy fans travelled to Abu Dhabi in much larger numbers than Chelsea, but the way in which Havertz and his team-mates celebrated demonstrated how important this was for Chelsea.
We trusted the statistics and I'm happy for him.
Chelsea sit third in the Premier League and are next in action in a London derby away at Crystal Palace next Saturday.
Do they possess the ability to completely own such areas of the pitch? Luan was then sent off to add insult to his personal injury, but the Blues deserved their win in the end, and the chance to complete their trophy cabinet.
The Palmeiras stopper pushed the ball around the post at full stretch, but Chelsea could make nothing happen from the resulting corner.
This is an amazing feeling for me.
