Chelsea manager Graham Potter has dismissed criticism of his temperament ahead of the Champions League showdown against Borussia Dortmund.
Joe Cole, Rio Ferdinand and Danny Murphy all questioned Potter's calm reaction to Chelsea's failure to win a penalty against West Ham on Saturday, claiming the Blues boss wasn't angry enough.
The 47-year-old refused to publicly condemn referee Craig Pawson, who refused to point to the spot despite what appeared to be a blatant handball by Tomas Soucek, during his post-match duties.
It was not the first time Potter's cool exterior has been called in to question since his arrival at Chelsea earlier this season.
