Thanks for all your feedback and comments this evening. With kick-off rapidly approaching it's time to focus on the game at a packed Goodison Park.
And Idowu Opeyemi writes on Twitter: "Good to see Mikel and Ramires together. Eto'o leading the line will make a big impact in this match.Chelsea to win by 2 goals."
Rhys Stevenson (who is the Editor / Owner of Global Metal Apocalypse) has been in touch to say: "First off Chelsea should have snapped Ozil up ages ago, look at his performance today! Stellar! But this is a must-win game, I reckon a 4-0 win with Eto'o getting 2 goals, 1 Mata, 1 Schurrle."
More from Sam Cox: "Two clean sheets but hardly the same defensive organisation as under Moyes, already looking open and shaky like Martinez's Wigan. Chelsea will need to be more proactive in attack than against Bayern and United."
Gareth Barry will make his debut for Everton today after arriving on loan from Manchester City and told Sky Sports 1HD: "I can't wait to get out there. It's always good to have that little bit of nerves. Chelsea have a fantastic squad."
David Hall, from Perth Australia writes: "I can see a 4-0, Torres to score a hat trick?" Could happen, David, but he'd have to do it from the bench...
Sam Cox reckons: "Will be a 3-1 win for Chelsea today, exposing Everton's newly Martinez-found defensive issues and a lack of punch up front for the Toffees." Pretty sure Everton have kept clean sheets in last two Premier League games, Sam?
Super 6 update: We have four people on track for the jackpot heading into the final match! Their Everton v Chelsea predictions are: 1-1, 2-2 and 2-1 to Chelsea.
Frank Lampard, who is not in the starting XI today, tells Sky Sports 1HD: "We will have to be at our best if we want to win."
The self-proclaimed 'Happy One' (who now often looks anything but) has told Sky Sports 1HD that Juan Mata remains a vital part of his squad despite his lack of action before today's start.
Chelsea fan Jordan Davies writes on Twitter: "Big target man Eto'o to make the difference today, Chelsea to win 3-1."
Stewart MacLaren has been in touch from "a warm & windy Torrevieja in Spain" to say: "Everton will draw 2-2 with Chelsea at Goodison Park this afternoon with good goals from Leighton Baines & Nikica Jelavic."
Julian Catt has been in touch to say: "Has Jose forgotten that Lamps always scores against Everton? Maybe he's saving him for later in what will probably be an evenly contested game. A draw looks the most likely result but I'm hoping we can edge it with Hazard the key player. Good luck to Eto'o on his debut too."
Chelsea fan Guy Edwards says: "Big game for us today, Eto'o needs to hit the ground running as we don't need a big star of the game over for one last big payday."
It will be good to see Samuel Eto'o get his first-ever taste of Premier League action this afternoon, while Chelsea certainly have strength in depth on their bench.
