Liverpool defender Joe Gomez says they'll be wary facing Brentford today.
Gomez is expected to start in the Reds back four.
He told Premier League Productions: “They have proven now they are a very good Premier League side.
“They have good individuals that speak for themselves, but as a unit I think they've created a real culture there that other clubs look at and pick things from. It won't be easy, for sure, we know that. But any game in the Premier League isn't easy and we've just got to try to prepare well and do the best we can."
He added of returning to the league campaign: “That's all we can do [move on from the Luton result], that's what we have to do. Obviously we had the Europa League in between and that sort of resets us in a way, but that's what the gaffer emphasises and that's where he leads by example - by dropping it so quickly.
“Reviewing it straight after the game, a quick meeting in the following days and then we're onto the next. That's probably the biggest thing in the game, if teams are able to do that and move on from a negative performance it will stand them in good stead."
