Dharamshala: In an apparent jibe at Test captain Virat Kohli's brand of aggression, India's limited overs captain Mahendra Singh Dhoni today said "exchanging words or physical contact" was not his idea of aggression and it was imperative for his team to play within the rules.

Test captain Kohli has been a big advocator of his brand of aggressive cricket while his premier fast bowler Ishant Sharma copped a one-Test suspension after his run-ins with the Sri Lankan batsmen during the final Test match in Colombo.
