Wahab reiterated Pakistan's plans to unsettle Root in Tuesday's news conference.
"You want me to tell you the plans? Every batsman has a strong point and a weak point and obviously you have to work hard on that and practise hard on that," said the 31-year-old left-arm paceman.
"Joe Root is the backbone of the England team and getting him out early will put the pressure on England. If he thinks it is just trash talk then hats off to him."
