Brentford's first home game next season will see former manager Mark Warburton return to Griffin Park for the first time since his departure in 2015.

The Bees were heavily criticised at the time for allowing him to depart, with Ian Holloway being particularly vocal, but two top 10 finishes subsequently have silenced the majority of those doubters.

After spending 18 months at Glasgow Rangers, Warburton left the Old Firm club in a manner still to be resolved before joining up with Nottingham Forest.

It means, then, that he will be returning to Brentford for the first time on August 12 and it is expected that, in the days leading up to the contest, a lot will be said about his time at Griffin Park.

To make things easier ahead of the run-up to the game, GetWestLondon has produced an explainer as to what we understand happened in the run up to Warburton's departure.

Indisputable facts

Mark Warburton was a successful manager at Brentford. That much is clear. He took the club up from League One and, in the Bees' first season in the Championship, they finished fifth.

Matthew Benham has Brentford's best interests at heart and the £90million he has put into the club has given him the right to run it how he pleases. Without him, the club would certainly not be an established Championship side.

Was Mark Warburton sacked by Brentford?

The popular myth is Mark Warburton was sacked and this is still claimed on social media. The short answer to this question is Warburton was NOT sacked.

The long answer remains in the negative but with certain caveats.

The club statement confirming Warburton's departure included the following: “There will also be a new recruitment structure using a mixture of traditional scouting and other tools including mathematical modelling.

“As part of the new recruitment structure, the head coach will have a strong input in to the players brought in to the club but not an absolute veto.”

Critics jumped on the three words 'including mathematical modelling' but that was not the overall reason why Warburton felt he could not work in the new structure.

The real explanation behind it all was the former manager would lose the veto – this was confirmed by Warburton prior to his departure.

Going back to the original question, Benham decided he wanted to change the way the club is run, as he has every right to do bearing in mind the money he has put into Brentford.

Warburton, sporting director Frank McParland and assistant manager David Weir did not want to work under the changes imposed on them.

The trio were NOT sacked but they clearly felt their positions were not suited to the structure Benham wanted at the club.

What led to the breakdown in relationship between Warburton and Benham?

The one-word answer to this question would be control.

There were a number of incidents and factors that led to the breakdown of relationship between the pair, which is still fractured to this day.

Both sides disagreed about how things were run on the training ground and in the transfer market and ultimately led to a breakdown in trust between the pair.

Saying goodbye: Brentford manager Mark Warburton

Benham's more analytical brain wanted things done in a certain way, for instance having a set-piece coach, whereas Warburton was not as keen on these methods. Harlee Dean said as much in the summer of 2015.

As previously explained above, Warburton felt the manager should have a veto on signings and there have been allegations, denied by the former boss, that he rejected potential signings in January.

Warburton is also alleged to have interviewed for the Norwich job, which went to Alex Neil, going behind Benham's back and was a major factor in the owner starting to looking elsewhere. I've always wondered, if this was the case, whether the owner wishes that he'd let him leave and his structure could have been introduced without the fallout that occurred.

When you think about it in a different way, none of this should be a surprise given Warburton's city background and Benham earning his money through his gambling business.

To succeed in the city and in business, you have to be head-strong and have the conviction that your methods are the right methods.

Indeed, the clash was so severe the pair had, by and large, stopped talking to one another.

Mark Warburton signed all of the players during his time as manager

Jota modelling the new home kit

This is not true. For one, a host of parties are involved in signing a player and it is incredibly rare for managers to just sign players on scouting reports or tell the club that they want him signed.

Jota, for instance, was a player found by Benham's analysts and brought to the club as a result by Frank McParland and he was a hit under Warburton's management. However, his best form actually occurred under Dean Smith last season.

The type of signings where the former Brentford boss would have played a lead role were for the players in Premier League academies such as Jake Bidwell and Adam Forshaw.

Warburton's experience prior to football management was in academy development and he headed up Watford's setup while establishing the short lived NextGen tournament, which was superseded by the UEFA Youth League.
