In Abu Dhabi 2016? Vettel did attempt to overtake Rosberg, but it didn't work out. See here at 2:55
I remember this race very well
He didn't insist, he could pass him, he was way quicker that's why he run so close to him in the straight given the nature of the circuit and the battle (Hamilton literally on his brakes) . This is just an extract but if you watch the whole sequence, you'll notice it . Some insiders (french media) in F1 did report this to Vettel and he didn't deny it
