Chelsea and Leicester played out a goalless draw at Stamford Bridge on Saturday, although the visitors will be wondering how they didn't manage to leave the game with more than a point.
The Foxes dominated the first half although they couldn't convert any of the chances they created against a below par Chelsea side, and despite going down to 10 men in the final 20 minutes after Ben Chilwell's red card, the host failed to produce any clear-cut chances in the 90 minutes.
Here are four things we learned following the stalemate at Stamford Bridge.
1. Fixture Congestion Taking Its Toll on Chelsea
Antonio Conte suggested his Chelsea side looked tired in the draw against Leicester, in what was their fourth games in just an 11 day period.
It is a new problem that Conte will have to contend with this season with his side still in four competitions, while last season, after their League Cup exit in October, they only had to focus on the Premier League and FA Cup respectively.
The size of Conte's squad is something that gets continually discussed, and with four games still to play in January in three competitions, before returning to the Champions League in February, the Italian may use the transfer window to add acquire some much-needed reinforcements.
2. Harry Maguire's Stock Continues to Rise
For all of Leicester's impressive attacking play, the away side never looked truly threatened by their hosts, thanks in no small part to Harry Maguire.
The 24-year-old did extremely well to marshal Alvaro Morata throughout the game, giving Chelsea's main striker virtually nothing to feed off, with the Spaniard cutting a forlorn figure during parts of the match.
The former Hull City centre-back exuded confidence whether it was in his defending, or bringing the ball out from the back with purpose, with Maguire's performances putting him in serious contention to make England's World Cup squad in the summer.
3. Chelsea's Star Performers Lost Their Shine
It wasn't a Chelsea performance we had been accustomed seeing during their game against Leicester, with many of Conte's main threats failing to deliver.
Eden Hazard, Cesc Fabregas and Alvaro Morata, three of Chelsea's main attacking threats, were anonymous for large parts of the game, with Hazard and Fabregas both getting substituted just short of the hour for Pedro and Willian in a game they needed to win to leapfrog Manchester United into second.
The issue this raises is the lack of creativity that Conte has at his disposal, because as good as Willian and Pedro are, they don't have the same creative influence that Hazard and Fabregas have, and usually when Hazard fails to perform, Chelsea fail to also.
4. A Game of Two Halves for Ben Chilwell
To use an overused footballing analogy, Ben Chilwell's performance on Saturday afternoon really was a game of two halves.
Leicester's left-back for the game, the promising Chilwell looked assured in the first period, continually getting up and down the touchline with pace and power, while the England U21 international provided some early opportunities that his teammates failed to convert.
The second half however proved to be a steep learning curve for the 21-year-old, who was given his marching orders after two yellow cards in the space of five minutes, the second for a late challenge on Victor Moses that he must learn from if he is to become the Foxes first-choice left-back.
