A.J. DeLaGarza has not been in Houston long, but you would not know it by how quickly he is figuring out Dallas is his new city's biggest enemy.

Most importantly, he has already figured out how to fight back.

On Friday night FC Dallas - the Dynamo's rival in the Texas Derby - hosted a party at which it unveiled a new road jersey for the 2017 season. This detail is important: The jersey has stars in the background in the chest area.

In soccer tradition, clubs put stars over the crest on their jerseys to signify how many league championships they have won. The Dynamo have two after winning MLS Cup titles in 2006 and 2007.

FC Dallas has had plenty of success in recent years, including winning the Supporters' Shield and the U.S. Open Cup title last year, but it has never won a league championship so it does not have any stars above its crest.

On its Twitter account Friday, FC Dallas posted a photo of a handful of its players in their new uniform laughing and included the caption: "Houston's actually a pretty nice city."

In most cases, the Dynamo would fire back. They didn't have to. The defender they acquired in a trade last month did it for them.

DeLaGarza quoted the Dallas tweet and replied, "That's nice they finally put stars on your jerseys. #WelcomeToTheRivalry"

With a mic drop like that, it is easy to see why DeLaGarza already is endearing himself to the Dynamo organization.
