The Australian speedy was left displeased following Grosjean blocked him near the start/finish straight, ruining his flying lap.
Ricciardo answered by giving the Frenchman the middle finger, but Grosjean claimed on team radio that he was told too late that the Red Bull car was incoming. However, the 28-year-old says it was just a heat of the moment thing.
“I had a bruised finger. I had an oversteer and was just shaking it off…” Ricciardo joked. “He didn’t need to do that, it was only practice so I am not fazed by it.
“It was a heat of the moment thing, for sure, but it was frustrating. I was on a hot lap and he was on an out lap.”
The Red Bull man also feels there is still work to do for Red Bull after the Friday practice and presently have no response to Hamilton’s pace out in front.
“Our short run pace looks pretty good,” he said. “Still not on Lewis’ pace, but fairly there with Ferrari. We know we will need to find a couple more tenths tomorrow.
“The long run there is a little bit more to find. A bit more work tonight, but generally not a bad day.”
