What happened: Roberto replaced Maya Yoshida, while Erik Thommy entered for Isaiah Parente. The changes brought two midfielders into the match at the same stoppage.
Why it matters: After leaving Como in June, Roberto gives the Galaxy a veteran with more than 400 appearances for club and country during his Barcelona tenure. The double change came with the Galaxy trailing 1-0.
By the numbers: Thommy's appearance followed a four-match absence caused by a foot injury sustained July 17.
What to watch: The next lineup will show whether Roberto is ready to move from the bench into a starting role.
