I remember that there was loads of Clemence v Reina chat when Reina was here.
I think part of it is that you always want to compare what you have to the best. Like if we have a really good holding midfielder then they must be the best in the world and one of the best ever. Or how for ages we compared every great side in Europe to how they would have done v the team that finished second in 09.
Ocassionally though, you do genuinely touch the Gods. Becker, Van Dijk and Salah are truly that.
