Australia fast bowler Mitchell Johnson quips that he thinks England batsman Joe Root has a cute smile.

Root has chosen to meet Johnson's "mind games" with a smile when batting against the fast bowler, but Johnson says he is comfortable with how batsman react as long as he feels in control.

Sledging has been frequently discussed during this Ashes series following Michael Clarke's fine for a confrontation with England bowler James Anderson in the first Test.
