Don't forget Yoel vs Costa. Thats 3 awesome MW fights.
From what I’m hearing Romero/Costa was a rumor and isn’t a definite:
“According to multiple sources close to Romero, though, he hasn’t agreed to that fight or any fight at this time. Romero had surgery on his broken orbital bone less than a month ago and, according to sources, he isn’t in a rush to accept his next fight until he fully heals.
[...]
Sources say Costa verbally agreed to the fight recently, but neither Romero nor his team have said yes to it, let alone signed a bout agreement.”
