The second of Sunday's London derbies comes from Stamford Bridge, where Chelsea take on West Ham.
Chelsea need to win to stay in the race for a Champions League place, and the Hammers need a win to pull away from the drop zone.
After 12 minutes of last Sunday's FA Cup quarterfinal against Manchester United, Rafael Benitez must have felt the axe swinging above his head.
With Chelsea 2-0 down to Manchester United, his own fans sang "You're just a fat Spanish waiter" to him.
Benitez had to make some brave decisions, and bringing on Eden Hazard shortly after half-time proved to be an inspired move.
The Belgian winger scored a terrific goal to reduce the deficit to 2-1 before Ramires equalised to ensure that both sides will have to go at it again in their quest for a place in the FA Cup semifinals.
Ramires has scored some important goals for Chelsea in the last year or so, notably at the Camp Nou in last season's Champions League.
He's someone who often slips under the radar, but he's a fantastic midfielder with a great engine and an eye for goal.
West Ham will have to work hard to keep him quiet on Sunday.
The best way to describe the Hammers' first season back in the Premier League is inconsistent.
They seem to play well in patches, but they make some awful mistakes sometimes, and if they do that on Sunday against Chelsea, they might well be put to the sword by the current European champions.
West Ham had a good win against Stoke in their last league outing, and Sam Allardyce will demand the same level of effort and commitment this weekend.
They're still without their captain Kevin Nolan, sidelined with a broken toe.
However, Matt Jarvis and Andy Carroll are capable of causing problems for the Chelsea defence, so West Ham have no reason to be fearful ahead of the game.
As far as the result is concerned, Chelsea's Europa League efforts might work against them and see West Ham earn a creditable draw.
Prediction: Score draw
