Chelsea head coach Enzo Maresca has refused to clarify comments that he is not getting support at the club.The Italian was asked to explain his claim made after Saturday’s win over Everton that the previous 48 hours had been his worst at Stamford Bridge but shut down multiple questions about whom he was targeting.Speaking ahead of Tuesday’s Carabao Cup quarter-final away to Cardiff, he became visibly impatient with requests for him to make sense of remarks that have fuelled intense speculation he was taking aim at the club’s owners and sporting directors.
