Joey Barton wasn?t impressed with Neymar?s performance against Russia and he showed his feelings on twitter after posting a tweet comparing the Brazilian sensation to a ?cat p**s?. Brazil faced Russia at Stamford Bridge for the international fixture and the game ended 1-1. Barton has insulted the young Brazilian in the past also by calling him over-rated. Neymar is one of the hottest prospects around and big clubs are after him. Here?s what he tweeted: Neymar is the Justin Bieber of football. Brilliant on the old You Tube. Cat piss in reality? — Joseph Barton (@Joey7Barton) March 25, 2013
