He quoted it to Espncricinfo 'Very arrogant' Virat Kohli motivated me to knock India out of World T20: Lendl Simmons http://www.espncricinfo.com/story/_/id/16019444/lendl-simmons-talks-playing-t20-west-indies-franchises-world 7 June, 2016
Context: When he (Virat Kohli) fielded, he said something to me, and I said to myself, 'I'm going to show you you're not the only good batsman.' That's the way he is. He's very arrogant, he's very aggressive when he fields, and when he bats as well. He's just a very aggressive person. Those things motivate our players and it certainly motivated me. That really urged me to bat the way I did - to show him that he's not the only one who can do it. That played a big role.
