Chelsea manager Frank Lampard wants his players to focus in their upcoming Champions League clash.
The Blues are facing off against Lille in the second game of the group stages.
And they know that it is crucial for them to get a win, given they lost their first game at home to Valencia.
Two defeats would put them on the verge of being knocked out before the round of 16.
Speaking about the upcoming clash, Lampard told the club's website: "We have to be honest. Valencia wasn't the worst game for us, we played okay and should've got a result, but it was a harsh lesson in switching off for a second and losing a match at this level.
"That idea ramps up even more when you play away from home at stadiums like this against top European teams. Lille have a lot of threats to us, particularly in attacking areas. They have a lot of speed and a lot of quality.
"It's not the be all and end all, there are four more games after this, we have to see the big picture, but as we sit here now it's certainly a game we have to be very ready for to try and pick up something.
"We can hopefully bring the confidence from the last two results back home tomorrow night. We have to trust that if we play at our best, we will get the result we want."
