After a superb start to the season, the last month has suddenly thrown up a few challenges for Chelsea.
In the wake of the defeats to Tottenham and Wolves, it became apparent that Maurizio Sarri is not yet working with the finished article.
However, back-to-back victories against Manchester City and Brighton have helped the Blues to keep Arsenal at bay in the race for the top four.
Claude Puel's Leicester represented the perfect opposition next up as the Frenchman is now under significant pressure.
The Foxes sat 12th going into the game, with Jamie Vardy among the manager's vocal critics as he has alleged Puel's style of play doesn't suit him.
Chelsea nearly got off to an ideal start when Harry Maguire's slip-up allowed Eden Hazard in on goal.
Uncharacteristically, the Belgian couldn't quite get his foot around it and he ended up hitting the crossbar.
The hosts continued to threaten, enjoying over 70% possession in the first half - but neither side could get a shot on target.
It has to be said that Willian didn't help matters.
The Brazilian so often proves a divisive figure among Chelsea fans and as he stepped up for a corner, he gave his critics further ammunition.
His effort was atrocious
It's one of the worst attempts at a corner you'll see this season:
Ouch. As much as the 30-year-old might have hoped it would be quickly forgotten, it wasn't:
It's not as if Sarri doesn't have any alternatives in Willian's position, but he seems willing to persevere with him for now despite another difficult start to the campaign from a personal point of view.
The irony is that the winger was heavily linked with both Manchester United and Real Madrid in the summer but remained at Stamford Bridge.
He'll have to do a bit better than that if he is to win a lot of Chelsea fans around.
