Mark Warburton has admitted a key element he couldn't agree to in Matthew Benham's new structure was the lack of overall veto.

The Brentford boss will leave at the end of the season, be it after the play-off semi finals against Middlesbrough or at Wembley, because he is not prepared to work within the owner's structure.

And the biggest element of it was being able to have a semblance of control when it came to recruitment.

He said: “I think that's important that the manager is the man who is picking the team and working with players.

“People play fantasy football, people look at it and wonder what attributes they need to be successful.

“It is a balance of young players and experience. I think the manager has to pick the team and have the final say in my opinion.

“When I was sporting director, my office looked over the training field it was the most frustrating two years of my life because I enjoy working with players and trying to impact young players but it's important boundaries are there.

“I couldn't tread on Uwe's toes. He had the final say in the team and the final say on players. I'd give my opinion and we'd argue every day.

"We had an honest relationship and we have to be able to work with players.”

Benham also wants to use mathematical models, which have reaped the benefits at FC Midtjylland, but Warburton was less concerned about these issues.

“I think there's going to be a much greater emphasis on mathematical modelling than currently.

“There are certain aspects which I think have worked well at this football club, but Matthew's the owner and the board have made a decision.

“That's the route they want to take. I have to respect it. I don't have to agree with it but I have to respect it.

“Hopefully all we can do is do our job here and hopefully that's enough to open up new doors come the end of the season.”

Many would have expected Brentford to fade after the parting of the ways was confirmed but, instead, did just enough to reach the play-offs and Warburton paid tribute to the staff for their efforts.

He added: “The staff I've worked with for seven or eight years or more, so we know each other really well, we're tight and focused and the respect within the group is very strong.

“It sounds a bit of a cliché but the day the news came out David Weir and my focus had to be this group of players, ably supported by a fantastic set of staff. We're in it together and hopefully that ill get us over the line.”

That said, when the time comes to say goodbye, Warburton will find it difficult given the relationship he has with them.

He admitted: “Yes, that's a frustration and disappointment, two overriding emotions, because they're a young group with lots more to come from them. That's the main ache.”
