Chelsea really struggled to break down Norwich City in their FA Cup Third Round tie and were left frustrated with a 0-0 draw at Carrow Road.
The two sides will meet again in a replay at Stamford Bridge after their stalemate which could be best described as a bore draw.
Neither goalkeeper had a serious save to make, but there was still a few things to learn about both sides from this match...
4. The Blues Lack Invention Without Eden Hazard
Eden Hazard has long been regarded as Chelsea's best player - that's not up for debate - but just how important he is to the team was on full display at Carrow Road on Saturday.
Willian provided a subdued spark, but Chelsea just lacked any real sign of creativity going forward and paid the price with neither Michy Batshuayi or Alvaro Morata getting a sniff all game.
Hazard makes them tick and can take any game by the scruff of the neck like any world class player can, but without him they look bereft of ideas.
3. Josh Murphy Will Follow in His Twin Brother's Footsteps
Josh Murphy was a fantastic outlet for Norwich until he was substituted late in the second-half, and was arguably their man of the match.
The Canaries' top scorer didn't look out of place up against some of the best defenders in the world and his pace to get in behind would be a key asset in the top flight.
His twin brother Jacob Murphy secured a £12m move to Newcastle in the summer, and many wouldn't be surprised to see Josh follow suit sooner rather than later.
2. Nelson Oliveira Looks to Be on His Way Out of Norwich
An hour and a half before kick-off, Nelson Oliveira was all set to lead the line for Norwich up front.
However, he ended up starting on the bench after ruling himself out. Norwich manager Daniel Farke claims this was because he had played seven consecutive games over a busy festive period.
1. Chelsea May Be Better Off Without David Luiz
This was David Luiz's first game back since he was banished by Antonio Conte for condemning his tactics.
And he didn't exactly cover himself in glory on his return. Sloppy mistakes at the back were something we hadn't seen from Chelsea during his absence, with a far more assured backline featuring Antonio Rudiger, Andreas Christensen, Cesar Azpilicueta or Gary Cahill preferred.
As great as his flamboyance can be - as seen with his close attempt from a long-range free-kick - Chelsea might be better off cashing in on the Brazilian to strengthen elsewhere.
