Rick Macci believes Serena Williams will make comeback, likely doubles with Venus Williams

The childhood coach of Serena Williams and Venus Williams thinks that the younger one will make a comeback by playing doubles with the older one.

Macci was the coach of both Williams sisters during their formative years and left a huge impression on both. He still follows them closely and he thinks that Serena might not be fully done with tennis. It's something she herself has alluded to even though for now she's not focused on anything tennis-related.

He responded to several fan questions on Twitter answering them all in one Tweet:

"Everybody is asking will @Serenawilliams play again. My answer is in doubles for sure with the one she has been skipping and holding hands with since age 9."
