I feel sorry for West Ham manager Manuel Pellegrini. He puts his team out one week and they are are really, really good. They look like a good top-10 side.
And then the next match they look like they have never met each other.
People might question Pellegrini's ability to motivate his players, but it can't be that. He will say the same things every week to get them going, and one week it works and the next week it doesn't.
I just don't get it - but it makes it very hard to predict the Hammers' results, whoever they are playing.
Chelsea have also been inconsistent this season, although not on the same level.
They come into this game on the back of two successive wins and, after being fortunate to beat Cardiff at the weekend, they were far more convincing against Brighton on Wednesday.
Blues boss Maurizio Sarri picked an interesting team against the Seagulls, with Callum Hudson-Odoi and Ruben Loftus-Cheek both starting, and after a performance like that why would you not start them both again?
If he leaves them on the bench on Monday then straight away the fans are going to be singing: "You don't know what you're doing."
Maybe Sarri is already thinking he won't be in charge beyond the end of the season so it does not matter. It does, though, because if he gets them in the Champions League it will go down as a good season for a new manager, whatever happens after that.
There seems to be a lot going on behind the scenes at Stamford Bridge, so if Sarri can secure a top-four finish then I would say that is a success.
A win for Chelsea would see them move back into the top four, at least temporarily. The Blues have failed to beat West Ham in their last three Premier League meetings.
West Ham have won four and drawn one of their last five Premier League London derbies.
Chelsea are unbeaten in their last six league matches at Stamford Bridge, while West Ham have failed to win any of their last seven matches on the road.
Chelsea are not quite looking like the kind of team that they are supposed to be of late and they don't have the most impressive of records of late against the Hammers, but surely this is a watershed match. With so much riding on the line, the Blues absolutely cannot afford to be dropping home points to teams as inconsistent as West Ham. The Hammers can do a job, sure, on their day, but a loss here could set up Sarri-ball to be over before it got started up in earnest.
West Ham are on the beach a bit as they are safe and going nowhere. They were very fortunate against Huddersfield when they won 4-3, that papered over the cracks, and then they got found out against Everton and if it wasn't for Fabianski it could have been any score.
I thought Chelsea were very good against Brighton, it's probably the best I have seen them play in a long time.
I expect Chelsea to win comfortably, but how many will be thinking about their Europa League quarter-final first leg on Thursday? Especially the manager as he hasn't won anything. Coming fourth in the league won't make a difference to him but winning the Europa is massive, so it will be interesting to see how he sets up.
He has an excuse with his team selection because he could turn around and say he is looking at Thursday. If you were him that's what you would be looking at. I think they might play their strongest team on Thursday.
Im expecting a home win here, and we’re not foreseeing a close game. Chelsea have kept a clean sheet in seven of their last 10 home league games, and the visiting West Ham have failed to score in five of their last six on the road. All of their recent defeats have been to nil, so backing Chelsea to Win to Nil here looks a great option alongside a 2-0 correct score prediction.
