They actually have a history together in the comics. For those of you that don't know, Thanos was the one who made Deadpool immortal. I really want this to happen. I'd like to see Deadpool and Spidey in the same movie too but Fox won't allow it :(
Knowing that i have been reading the Deadpool comics for a bit more than 10 years now... that i waited around 5 years for the movie (that took Ryan Reynolds 11 years to make) AND that I love the fact that he and Thanos are competing for Lady Death's love (knowing that Lady Death loves Deadpool) AND that Deadpool and Thanos fought a couple of times... OF FUCKING COURSE i wanna see Thanos vs Deadpool in the Inifity War movies
I mean Thanos sort of seems like a boring villain. Unlike Loki and Ultron, which were interesting and honestly incredible and intimidating (lots of "I" words) I don't know much about Thanos, but all he seems to be is power.
