On the City stadium and academy tour, the guide motioned towards the hand sanitisers either side of the players pitchside entrance.
They had small pieces of tape on them - leftover from the previous days CL match, covering the very very small logo of the hand sanitiser just because it wasn’t one of the CL’s official sponsors.
Just in case a camera would catch and zoom in on them… causing the collapse of the exclusivity of CL sponsorship… unbelievably petty for such a small thing (I can understand Etihad stadium branding), and I doubt (and hope) there wasn’t even an official CL hand sanitiser sponsor.
