Everton defender Michael Keane reiterated his manager's words and called for the team to emulate last season's impressive home form, when they lost just two of their 19 league matches at Goodison Park.
Speaking ahead of Thursday's game, Koeman said: "We know the situation in the group that we need a win".
"We spoke about football", said Koeman, who came to Everton last season after a successful spell at Southampton.More news: Central Intelligence Agency bomb-sniffing dog flunks out of training in Twitter saga
"If we have a good game and finally have a good result then preparation for Sunday will be easier".
The Toffees have won only two of their last 11 matches across all competitions, while just two league victories sees the Merseysiders languishing in 16th place in the Premier League, two points above the relegation zone.
Everton are still without long-term absentees; Ross Barkley, Yannick Bolasie, Seamus Coleman and Ramiro Funes-Mori and whilst James McCarthy played 45 minutes with the under-23 squad, he won't feature against Lyon.
JonJoe Kenny remains a doubt for the fixture with the Ligue 1 side, after he picked up a knock during worldwide duty with the England Under-21's, but had returned to training on Wednesday.
