Found this gem, need your help

So sorry for the re post, I had really bad connection so sorry if you have seen this post before.

To re cap, i found this Everton GK shirt from the 2000-01 season. I don't have many GK shirts and this is a really nice shirt

I cross checked online and it looks good, but I would love for some of you experts to help me verify, the authenticity of this shirt. It is about 45 GBP after conversion.

Thanks a lot guys so sorry if I bothered you. Cheers
