Andre Villas-Boas believes that the rivalry between Tottenham and West Ham United is great but has warned fans not to make it worse with their behaviour.
Anti-semitic chants were heard all around White Hart Lane as Spurs beat the Hammers 3-1 today and although Villas-Boas did not want to comment directly on that issue, he did urge supporters to be careful that they do not tarnish the competitiveness between the two London clubs.
"I prefer not to mar the performance with a situation like this," Villas-Boas said.
"You know the animosity there is between Tottenham and West Ham and as long as it doesn't reach stupidity it is a great, great rivalry of two London clubs.
"It would be extremely unfair for me to mar the performance of the players but understanding that a couple of situations are avoidable but we can't decipher the true meaning of what they were saying."
