Everyone might want to face Manchester United at the moment, but their trip to Chelsea spells serious danger for Xabi Alonso.
The Blues boss has flown under the radar somewhat since his arrival at Stamford Bridge.
After a chaotic, entertaining start and some encouraging wins over Bournemouth and Everton, it has all fallen quite flat.
An embarrassment at home to London rivals Tottenham, the butt of the joke in the Premier League of late, was followed by a Carabao Cup exit at Liverpool.
Another failure against this toxic and terrible Manchester United would seriously put the heat on Alonso.
Most of us would expect United's downward spiral to continue the way things have been going in recent weeks.
However, we have seen over their years of struggling that, once the spotlight is turned on them, these Manchester United players can pull a performance and a result out of the bag when it is least expected.
But no one would consider that when putting Alonso under the microscope.
And would it really be a massive surprise if United leave west London with smiles on their faces and three points? No, because Chelsea cannot keep a clean sheet.
They have just two this season, against Everton and Luton Town. Given their expenditure at the back it is very poor.
There are plenty of little signals to encourage United. Pedro remains injured, Maxence Lacroix is too and there is still no Emiliano Martinez.
It looked like Chelsea had turned a corner after their win over Everton, but now there are problems piling up and in goal they look to have someone, in Mike Penders, who cannot catch a ball again.
Like I said, a lot to encourage United to make a fast start and put them under pressure.
When Alonso arrived there were goals galore and we were looking at the most exciting front three in the Premier League with Joao Pedro, Cole Palmer and Morgan Rogers.
People were, foolishly, tipping them to give Arsenal a run for their money in the hunt for the title.
But they were absolutely shocking at the back, and while there were injuries some of that has to go on the manager.
Those injuries mean it is hard to see exactly what Alonso wants them to be as a team. When you consider that the benefit of not being in European means there is so much more time for him to work with those who are fit, that has to be a concern.
Given where they are in the Premier League table, fifth and two points better off than Brentford having played fewer games in all competitions than everyone above them, that is not a lot to have sacrificed European football for.
Alonso is yet to face any real pressure or sustained heat from the fans, but this weekend could be the turning point.
The Spaniard arrived being hailed as the man to bring serious standards and professionalism to a petulant squad packed with potential. But that has not quite settled in yet either.
Attempts were made to add experience and move on some unruly characters, but that ideal is still being undermined by some silly players.
Palmer lost his head against Tottenham and was sent off. Rogers was fortunate not to get a second booking at Everton and arguably also lucky not to join Palmer in being given his marching orders against Spurs.
We are seeing too many of the same old Chelsea problems and Alonso must find a solution, fast. Not that his selections or comments over the past week have gone down too well.
Playing Rogers through the middle against Spurs was daft, when have we ever seen him look good doing that or want to play in that position? You are taking away the best of a player you broke records to sign by doing that.
They would never stick Moises Caicedo up there, would they?
And to add to some growing pressure from the fanbase, after going out to Liverpool this week Alonso said the quiet bit out loud by suggesting it was alright because the Carabao Cup is not that important anyway.
A strange thing to say.
We are a long way from serious, Michael Carrick-style questions being posed to Alonso, but he will be more aware than anyone that the honeymoon is well and truly over.
