New Leeds United boss does not take transfer failure lightly.
More than a week since Marcelo Bielsa's official appointment at Leeds, fans are still waiting for the club's first signing.
Work is clearly ongoing behind the scenes, and sporting director Victor Orta is a man under pressure.
If Leeds do not get it right, Bielsa is not afraid to take the club on publicly and call them out on failure.
He quit Lazio after just two days over differences, and his spell at Marseille got off to a rocky start too.
We took a look back at Bielsa's brilliantly scathing press conference in 2014 in his first summer at Marseille where he attacked the club board after failing to land any of his targets.
It is an approach which should instil fear into Leeds chief Victor Orta if he does not deliver.
Marca reported Bielsa saying, "My assessment of this transfer window is a negative one. I think the president made me promises he knew he could not deliver on.
"None of the players signed were requested by me. We wanted Stambouli or Alderweireld. I found out about the sale of Lucas Mendes to Qatar at the last minute. I found out about the signing of Doria when he was undergoing his medical. I didn't want him.
"None of the players who have joined were my requests. I proposed 12 names and none of them came through. I asked for Jara, Manquillo, Isla, Montoya, Coke, Ocampos, Rekik, Aurier, Tello, Medel and Stambouli. We had to rush our business despite the fact we knew who we wanted."
There is so much to unpack here in terms of the candour Bielsa offered reporters.
He publicly called out his club president, and admitted to not wanting to sign one of his players.
Bielsa reeled off a list of players he wanted to sign, while also claiming a player was sold without his knowledge.
If Leeds have done their research on Bielsa, they will know not to do any transfer business behind his back, as he will publicly call them out on it.
Fail to get his top targets too, and he will feel equally aggrieved.
No pressure Victor...
