Chelsea earned a hard-fought point against Manchester United with a goalless draw at Old Trafford on Saturday.
The Blues looked solid in defence throughout, aided by the returning Thiago Silva in the back three.
Manager Frank Lampard was convinced his side should have been given a first-half penalty after United skipper Harry Maguire appeared to wrap his arm around Cesar Azpilicueta's neck in the box. The incident was reviewed by VAR, but it came to nothing.
Lampard said: "I thought it was a clear penalty. Holding is allowed, but headlocks aren't.
"Obviously I didn't see it at the time from where I'm standing.
"They are hard calls for referees on the pitch, but the VAR was very quick to dismiss it in my opinion.
"I think they should have taken time and advised the referee to watch the monitor. If the referee goes to the monitor, he gives a penalty."
The game was a rather drab affair, with a combined five shots on target in wet, difficult conditions.
New signing Edouard Mendy proved his worth in goal yet again, saving superbly from Marcus Rashford, twice, and from Bruno Fernandes.
Chelsea return home in sixth place in the League with nine points, whereas United sit two points back in 15th - highlighting just how close the table is at present.
In the grand scheme of things, Chelsea will probably be the happier of the two sides, thanks to a clean sheet and a point at their rivals.
Here is how the Chelsea dressing room reacted to yesterday's draw on social media.
Azpilicueta said the team will continue to grow, Silva praised their "fighting spirit", and others highlighted the importance of coming away with a point.
Chelsea kept their first Premier League clean sheet outside of London since a goalless draw at Leicester on the final day of the 2018/19 season under Maurizio Sarri.
Mendy became the first Chelsea goalkeeper to keep a clean sheet in both of his first two Premier League games for the club since Petr Cech in August 2004.
Despite playing just half of Chelsea's six Premier League games this season, Ben Chilwell has created more chances than any other player for the Blues in the league this season (9).
Next up for Chelsea is FK Krasnodar on Wednesday in the Champions League.
