I would like to discuss with you guys whether defenders in soccer are underpaid. Well, I guess obviously. No defenders made it to the top 10 most expensive transfer in the world football transfer record. The closest is David Luiz in 2014, which costed Paris Saint-Germain around £50m. It is sad how we value scorers way above defenders. I do think we should pay defenders more respect and money. It is so unfair to them as we are implying they contributed less comparing to midfielders and strikers.
