66 min: Sergio Aguero is hooked. Gabriel Jesus replaces him. And then on the touchline Aguero instigates a hard and fast discussion with his manager. For a second, it looks like Pep is about to cuff his player around the lug, but he’s ushered away from the situation. It all calms down quickly enough, anyway. All good pantomime fun, which will no doubt be blown out of all proportion later.

It looked like Pep was going to box Kun's ears but will be "blown out of proportion"? What is the proportion?
