Any football shirts originating from Thailand, or Asia for that matter, are also fake. Thailand is literally the world's hub of fake football shirts.
And finally, if you obtain football shirts from an unofficial source (a source that is not endorsed by the club or sportswear brand owner) you should:
1. investigate the provenience of the football shirts (this will often mean that the wholesaler has to reveal their source to you, by showing you their purchase invoice from the original source, which they be reluctant to do unless they know you well)
2.order a sample for inspection (then compare it with an official football shirt purchased from an official store)
3.check that the football shirts feature the original logo from the football association of the club's country.
