The O's secured their place at the top of the National League on Saturday with a 3-1 win over Chesterfield at the Breyer Group Stadium.
Here are the five things we learned...
1. Josh Koroma does Josh Koroma things!
The O's youngster continued his fine form on Saturday with another goal, scoring the a very Josh Koroma-esque goal as he picked up the ball on the left side of the box, cut inside and drilled home. Our opponents tried to force him out of the game by heavily marking him but the 20-year-old was a menace, particularly when dropping out to the left side.
2. Charlie Lee's aerial threat
The midfielder made his first appearance since the victory over AFC Fylde in November and was notable for the impact he had defensively. With 6ft7' striker Tom Denton up-top, Chesterfield naturally opted for a largely aerial bombardment but Charlie Lee proved instrumental, defending from in-front of the forward with his early jump and strength making Denton's life particularly difficult.
3. Sam Ling is back!
The young full-back has won praise from Justin Edinburgh in recent weeks as he put his body on the line and rushed his recovery to take the injured-Myles Judd's place at right-back but his performance on Saturday was his best yet. Defensively solid and constantly providing an option going forward, he is proving why there will be serious competition for that spot in the second half of the season.
4. Joe Widdowson is the unsung hero
Meanwhile, the other full-back continues to go about his business with satisfying consistency. Joe Widdowson has been an absolute rock at left-back and was instrumental in Saturday's win - good in the air, good on the ball, good at defending.
5. Left, Right, Left, Right
In the midst of Manchester United's win over Cardiff, England star Jesse Lingard picked up attention for his celebration called the 'gun lean', inspired by the rapper Russ. However, O's winger Koroma used the celebration a full three-hours before, as spotted by the Daily Mail. Who did it better?
