Are you really a professional footballer if you don’t change your hairstyle every other week or are covered in tattoos?
Of course, there are still a few ‘old school players’ that persist with the short back and sides and don’t have any ink on their body - we’re looking at you, James Milner.
A certain haircut or a tattoo sleeve doesn’t affect your footballing ability and, as football fans, we shouldn’t really care about the appearances of players.
But some people do care - maybe a bit too much.
And one person that really has let it bother him is good old Garth Crooks.
Crooks is renowned for picking BBC’s Team of the Week on a Monday morning and, at the same time, is usually trending on Twitter.
When he’s not putting players in the wrong position, he’s moaning about their hairstyle.
That’s what happened this week.
Crooks moans about Bakayoko
After putting Chelsea defender Cesar Azpilicueta in his team Crooks explained that after inheriting the captaincy at Stamford Bridge, the Spaniard should have a word with teammate Tiemoue Bakayoko.
"I just wish the Chelsea captain would tell Tiemoue Bakayoko to come to work suitably turned out," he wrote.
"The time and effort it must take the Frenchman to manicure and dye his hair - it was blue this week, and I dread to think what colour it will be next week - could be far better spent either on the training pitch or perfecting his English.
"The great Ruud Gullit said he spent most of the time sleeping off double training sessions and had no time for niceties when he was a player. That is clearly not the case for Bakayoko, who clearly has too much time on his hands and dye in his hair. And Azpilicueta should tell him so."
For starters, Crooks clearly wasn’t aware that the midfielder promised to dye his hair blue when he scored his first goal for the club - which he did against Crystal Palace a fortnight ago.
And secondly, why does Crooks care so much?
Crooks on Fernandinho
But he wasn't finished there. He continued his rant when he included Fernandinho in his XI later in the BBC article.
He added: “Fernandinho is a model professional; no flashy haircuts, and certainly no dye in his hair. He doesn't come to work as though he's auditioning for a modelling job on a Paris catwalk, or attract unnecessary attention to himself.
"In fact, the only attention he attracts is for what he does with the football, and that's the way it should be. That is why, since his arrival at Manchester City, every manager has selected him on a regular basis.”
Unsurprisingly, football fans were all asking why Crooks cares so much as they slammed him for his bizarre comments. Check out the reaction:
But this isn’t the first time Crooks has moaned about hairstyles. Last month, the pundit admitted he was irked by Paul Pogba’s hair.
"I also want to discuss Paul Pogba's new hairstyle, which features a red streak." Crooks told BBC Sport.
"I only mention it because he clearly wants to bring it to our attention. There is so much for the midfielder to do at United and he still insists on behaving like an adolescent.
"Granted, a hairstyle is not going to determine how well he can control a ball or make a pass, but it does say something about where his mind is at the moment. If you are going to attract attention to yourself on a football pitch do it with goals and performances, not cheap gimmicks and marketing tricks."
Let it go, Garth.
