A few observations:
1. You can't spread Covid-19 unless you've got it. (Yes, I know that many people are asymptomatic but you still can't spread if you've not got it at all). Professional footballers are regularly tested to check that they've not got Covid-19, and it seems that the hairdressing undergoes regular testing too, so the chances of Covid-19 passing from one to to the other are virtually zero ;
2. You can't be a 'superspreader' in a one-to-one environment. It simply goes against the very definition of the word ;
3. From a statistical viewpoint, a guy who makes a one-off trip to a hairdresser's salon (where he'll be on his own, apart from the presence of the hairdresser) is probably far less likely to catch or spread Covid-19 than people who still insist on doing their supermarket shopping every day, and across several different stores, rather than trying to get everything in just one store (at a time when it's very quiet) no more than once per week ;
4. He's not even in the same league as many others are when it comes to putting people at risk:

None of that means that he was right to get his hair cut professionally. He wasn't. However Canary42 seems to have a downer on well-paid professional footballers simply because of who they are, rather than because of their specific actions.
