Leyton Orient have certainly had their trials and tribulations over the years.

Since the turn of the millennium the O's have competed in League One, League Two and the National League as the East London club have seen their EFL status lost and found once more.

While off-field matters have played a huge part in that there's no doubting that key men on the footballing side of things have played a big role in the club's ups and downs over the years.

During the last 20 years there's been some memorable managerial reigns, and unfortunately some not-so memorable ones, but who are Leyton Orient's best managers according to PPG (points per game)?

We took to Transfermarkt to find the top 10 since the year 2000.

Number 10 on our list, according to PPG.

Davis was appointed as head coach in July 2017 following the club's relegation out of the EFL and into the National League.

Unfortunately for him and Leyton Orient things didn't quite go as well as they'd have hoped.

The O's won just five of their 19 league matches in the opening months of the season leading to Davis being sacked in November that same year.

Results were so poor that the head coach only managed a PPG of 0.75 per game.

The Italian comes in at number nine in our list.

Liverani took charge of Leyton Orient in December 2014 with the club competing in League One.

The O's had narrowly missed out on promotion the previous year but the 2014-15 provided plenty of issues with the club eventually going on to be relegated to the fourth tier.

Liverani was in charge of the team for the second half of the season but left his position by mutual consent after relegation was confirmed in 2015.

Turns out a PPG of 1.11 wasn't enough to see the club to safety.

The Welsh manager is number eight on the list.

Williams was appointed as Leyton Orient manager in February 2009 and got off to a very impressive start after guiding the team to seven wins from their first nine games.

Despite being tipped for relegation from League One he defied the odds and helped the club to avoid the drop - leading them to a safe mid-table finish instead.

However Williams would last little of a year in charge after walking away from the job in April 2014.

A PPG of 1.25 was far from spectacular, but given expectations at the time it was seen as a decent return.

A man who has stepped up for Leyton Orient in some of the most difficult circumstances.

Despite taking interim charge on several occasions Embleton was appointed as permanent head coach in January 2020 and tasked with helping the club to avoid relegation from League Two.

The O's secured a 17th place finish last season but lasted just over a year in charge.

Embleton was sacked last month following a run of poor results and replaced by Jobi McAnuff as head coach.

A man who is fondly remembered by supporters, Embleton has a PPG of 1.25.

Number six on our list with a PPG of 1.31.

The former midfielder took charge in December 2003 with the club competing in the old Division Three where he avoided relegation in his first season.

Steady improvement under Ling saw Leyton Orient secure promotion to League One before consolidating their position for two season in the third tier.

Ling left the club in January 2009 before going on to join Cambridge United later that year.

Of course the 54-year-old has since returned to East London and is now working as director of football for the club.

Number five on our list is Ian Hendon.

The former defender enjoyed a great playing career with Leyton Orient and returned to the club as manager in May 2015 following the club's relegation from League Two.

Unfortunately for the club favourite his time back at the club was short-lived.

Hendon was sacked in January 2016 after a poor run of results that equated to a PPG of 1.31.

Despite hoping for promotion Leyton Orient failed to go up that year and ended the season in eighth position in the National League.

The 55-year-old ranks at number four on our list.

Hessenthaler joined Leyton Orient as assistant manager at the end of the 2014-15 season and took full charge of the first team in April 2016 after replacing Kevin Nolan as boss.

Unfortunately his time in the hot seat didn't exactly go as well as he would have hoped.

Hessenthaler only stayed in charge until September that year after taking charge of just 16 matches for the O's.

However he's bounced back and is currently managing Dover Athletic.'

Number three is probably the highest-profile name on the list.

Nolan was announced as player-manager of Leyton Orient in January 2016 with the club looking to secure promotion from League Two.

Things got off to a positive start under the midfielder with the O's winning three of their first four matches and Nolan being nominated for February's manager of the month award.

However that success was short-lived with Nolan's reign being brought to a premature end.

He was relieved of his managerial duties in April 2016 and left the club entirely just a few months later with a PPG of 1.53.

It's Russell Slade who takes the number two spot on our list of most successful managers by PPG.

Slade was appointed as manager in April 2010 with just a handful of games remaining in the season - a campaign that saw Leyton Orient finish in 17th position after enduring a relegation battle.

The O's then finished in seventh position the next year, 20th the following, and seventh again the year after before Leyton Orient mounted a genuine challenge for promotion in Slade's final season with the club.

But after finishing third in League One the club lost in the play-off final against Rotherham United.

It wasn't long after that that Slade left the club but with a PPG of 1.55 few can argue at home much progress the club made during his time in charge.

There's only one man who could take top spot in our rankings.

Edinburgh was appointed as Leyton Orient manager in November 2017 with the club competing in the National League.

After a season of consolidation in 2017-18 the next year saw the O's push themselves to the top of the table and secure promotion back to the EFL after two difficult seasons away.

Edinburgh was seen as the perfect man to help the club acclimatise to life in League Two but sadly passed away in June 2019 after suffering a cardiac arrest.

It's easy to look back with rose-tinted glasses but with a PPG of 1.83 there's no question that Justin Edinburgh is the deserved recipient of the top spot in our top 10 list of managers according to points per game.
