Dernbach criticised for poor sledging

Australia batsman David Warner has used his Twitter account to criticise English paceman Jade Dernbach.

After watching Dernbach verbally abuse a batsman on TV in the Big Bash, Warner said: "Dernbach should worry about bowling before trying to sledge. He had a go at me as well."

Dernbach has figures of 0 for 80 in eight overs so far.
