Stoke chief's tackle anger
Stoke boss Tony Pulis described David Luiz's challenge on Jonathan Walters as "dreadful" and feels the Brazilian escaped a red card.
Luiz, who signed a new deal with Chelsea over the weekend, was involved in an incident with the Potters forward towards the end of the match at Stamford Bridge.
Walters was caught on the ankle by what looked like a two-footed challenge from the Blues defender, and the Republic of Ireland international acted angrily when he got back to his feet.
Referee Michael Oliver only booked the Brazilian for the challenge, a decision which angered the Stoke manager - who saw his side lose to a late Ashley Cole goal.
Pulis said: "It's a dreadful challenge. You expect a referee of Premier League quality to deal with it."
Chelsea boss Roberto Di Matteo play the incident down, saying "It is a strong tackle. Fortunately it didn't catch him 100%, but the referee made the decision and we accept that."
