"I get along with Shane very well. I thoroughly enjoy batting with him, I know what he does for the team and I know what a team player he is," Warner was quoted saying in the Sydney Morning Herald.
Warner, who scored 193 runs for Australia A against South Africa A here Wednesday, has come out in support of Watson after his brother Steven Warner had hit out at the all-rounder on Twitter.
"Not just on the field but in and around the group how he supports the guys. He's fantastic. I just can't get enough of him," added Warner.
Steven blasted Watson July 19 for wasting a review at Lord's by tweeting: "F---ing selfish Watson sooner your out the side you great pretender the better."
"I had absolutely no idea. I got a call from Pat Howard, high performance chief, about it and I was dumbfounded because I hadn't checked Twitter in ages. He's had his opinion. I've had nothing to do with it, no idea about it at first. He's deleted his account," Warner said.
Warner defended his brother saying he was only having his say but was disappointed at his remark about Watson.
"It was very disappointing. I've actually had a good word to him and he was shattered. He obviously didn't know that his opinion would be judged like that and he now knows that. He got a good kick up the bum by Mum and Dad as well," he said.
