Given that Rocky was dealing with cancer during Creed, it's unlikely that we'll see him and Ivan Drago back in the ring punching the hell out of each other, especially if Drago's been keeping in shape. That said, Drago did kill Apollo Creed, Adonis' father and Rocky's best friend. More than three decades have passed since that event, but if Drago still doesn't feel remotely remorseful about that, then one would imagine that Rocky wouldn't hesitate socking him in the face. You can be damn sure that Adonis also holds a grudge, but in terms of Creed 2's main event, there's been speculation that Michael B. Jordan's character might fight Drago's son. One can only hope that Drago Jr. hasn't been juicing like his dad did back in the day.
