This assist from Roberto Firmino to Mohamed Salah for Liverpool's second goal against Southampton is everything. After scoring the first via a Salah assist, Firmino returned the favor in style. The match ended 2-0 to Liverpool, with Firmino's assist the major highlight.
Teams seem to forget about Firmino until he pops up in a dangerous area and embarrasses any and all defenders who stand in his way. This is a perfect example.
Now, if you'll excuse me, I'll be watching this assist and goal over and over and over again.
