Liverpool will play Brentford at home. I don't see anything positive for the visitors in this match, and I think Liverpool should comfortably take all three points. Liverpool won their first match against Ipswich 2-0, although the game was tougher than expected. Brentford also started the season with a win, beating Crystal Palace 2-1. It will be tough for Brentford against a much stronger Liverpool. Even if Klopp experiments with the lineup, I expect plenty of goals.  
My prediction: a Liverpool win.
