But Niasse, frozen out for much of last season by Koeman, came off the bench to score twice in his first appearance for Everton in the Premier League since May 2016. I have found Everton to be like Sunderland, from the point of view that it is a family-orientated club with a huge fanbase and a passionate following.
But boss Koeman has reminded the rest of his squad to remain on their best behaviour in order to fully focus on turning around Everton's poor start to the season.
In the absence of more established names, the likes of Dominic Calvert-Lewin, Nikola Vlasic and Jonjoe Kenny all showed that they have something to offer in the three-game run at Goodison over the next week.
Ronald Koeman restored Davy Klaassen, Wayne Rooney, Leighton Baines and Gylfi Sigurdsson to the starting line-up but Everton toiled in familiar fashion the first half, registering just one shot on target as the two sides largely cancelled each other out.
And Howe's frustration was compounded when James McCarthy and Lukaku, again, struck to send Everton into the break with a three-goal advantage.
Bournemouth breathed life into their Premier League season with a valuable home victory over Brighton in front of the television cameras last Friday night.
Ex-Everton midfielder Dan Gosling could be the player to miss out if Howe chooses to persevere with the new system.
Golovkin, Canelo finally take over spotlight
The fight with Cotto represents arguably the Mexican's biggest victory and saw him claim the vacant WBC world middleweight title. Due to piracy laws and with all the money at stake for big fight PPVs, it is becoming increasingly hard to get a reliable link.
For the visitors, defender Tyrone Mings is out for at least a month with a back issue.
Ronald Koeman: "The first step was yesterday".
"More credit to the players - Niasse and Davies". That is this Saturday.
"We were good today", he added. Personally, I think Joe Hart is a great goalkeeper and someone I looked up to when I was younger with the pathway he took to get to where he has.
The third-round victory came at a vital time for the Blues, stopping a worrying trend of six consecutive fixtures without a win, including shipping 12 goals in their previous four games without finding the net themselves.
Raheem Sterling's quickfire second-half brace put the result beyond any semblance of doubt and an overworked Wayne Hennessey in the Palace goal was unable to keep out Sergio Aguero's 79th-minute header from Sane's cross. In the Premier League, you can't give yourself a mountain to climb and you can't start so badly that you are in a position where you are playing catch-up because it is such a tough league.
Calvert-Lewin, who has four Everton goals in total, made headlines over the summer as he scored the victor for England in the Under 20s World Cup final.
