It's less likely with Rafa now, as his offence is never as penetrating as 'Fedringka', at his best he can nearly match Djoker as their playing style is a lot more similar, and then they get into physical war with each other - not the case with Fedringka, they either hit through Djoker or they break down with too many errors. In Rafa's favour though, he would make up with his unsurpassed mental fortitude in a dog fight, but firstly he needs to play well enough to make it a dog fight against Djoker. at the moment his own level is too low to even think about that, and given his mileage/wear and tear despite only being a year older, his chance to get back his best level is very ......... slim.
