The Blues have sputtered as of late, coming off a 2-0 loss at Manchester City that eliminated them from the FA Cup. They also came up with a disappointing draw at West Brom in their last Premier League action but were able to maintain the league lead.
Everton are still chasing a top-four finish as they sit in sixth place in the table, eight points back of fourth-place Liverpool and 12 off table-leading Chelsea.
Let's break down the upcoming matchup in Stamford Bridge.
Where: Stamford Bridge, London, England
When: Saturday, Feb. 22 at 7:45 a.m. ET/12:45 p.m. GMT
TV: NBC Sports Network, BT Sport (UK)
Top Storyline: Will John Terry Return Spur Title Run?
Chelsea will get their captain back from injury in Saturday's tilt against the Toffees as Jose Mourinho has stated, according to ESPN FC's Miguel Delaney.
The 33-year-old is entering the twilight of his career but still started Chelsea's first 24 league games. However, he's missed the team's last two EPL matches as well as the FA Cup loss to Manchester City.
Terry's return comes at the right time with the missing of an injured David Luiz in the backline, per Mourinho via the club's official site:
David Luiz is injured, he's feeling some pain in his muscle, he's not ready for this game but hopefully he will be ready for the next one. The next game is in the Champions League where we will have two players less than normal because [Nemanja] Matic and [Mohamed] Salah cannot play. We need him, if possible, to be ready for Galatasaray.
His re-insertion into the lineup needs to make a big impact in the Blues squad, which is gearing up for the last 12 games of this season that could very well end with a Premier League title if they focus right.
Terry is one of the players on the squad still around from the 2009-10 title win. He knows what it is like to go through the rigors of a season, while saving the best for last and closing out with a resounding title.
He also likely knows from observation that this year's Premier League is there for the taking. No club has really proven themselves to be the frontrunner, although City and Arsenal have both shown shades of being that.
Chelsea's draw versus West Brom could be one of two things. It could be the start to the Blues' downfall and a series of disappointing results, or it could be motivation to close the season with a championship.
Terry plays the biggest role in that run. If he is able to use his experience and have it rub off on his fellow teammates, Chelsea could be bringing home a 2013-14 Premier League title to Stamford Bridge.
With the Blues set to travel to Turkey this week to face Galatasaray in the Champions League, Chelsea must not get caught looking ahead and take care of business to stay atop the EPL.
Chelsea were dealt a big blow during the week as they were eliminated from the FA Cup, but this club has their focus solely on grabbing a league title.
Mourinho's squad will be boosted by the return of Terry, who hasn't played for Chelsea since early in the month. If Eden Hazard continues his recent goalscoring prowess and Samuel Eto'o steps up in likely starting duty, expect the Blues to grab three points at home.
