Mauricio Pochettino says the managerial hot seat is like an electric chair - and that you'd have to be "crazy" to sit in it.

Last week's defeat away to Everton resulted in the Argentine manager losing his voice after shouting at this players, but he has bounced back to a more upbeat tone ahead of Saturday's meeting with Sheffield United.

Pochettino laid into his squad and club hierarchy after losing on Merseyside with a squad that has received £1billion of investment but is marooned in mid-table before the visit of bottom-club Blades.

Asked about the pressure on himself ahead of the game, the 51-year-old admitted: “I am crazy - a little bit - all coaches are.

"We want to show we are normal people but we are not normal. That is why we are here. This is an electric chair!”

Pochettino added that it was not his "intention" to "create a big mess" and sound so critical of the project after losing at Goodison Park, which has left Chelsea closer to the relegation zone than the top four. The Blues boss nonetheless insisted he "trusts" Chelsea's vision despite their struggles.

“I am a person that always trusts and trusts until someone shows me I cannot trust anymore,” Pochettino insisted to reporters at Cobham Training Centre.

“But I trust, I trust. Of course, I also know that I need to deliver in the job, and of course, it’s not only you need to deliver, but also to get some results. I know how it is in football. I trust, I trust, I really trust. That is why I am here.”

He added: “The communication is the same from the beginning of the season when we were in pre-season to today. Of course, it is the same communication. But no words [are not important] in football.

“The most important thing is being here. If I am here, it is because [the owners] trust. If at any moment they stop trusting, don’t worry; you will not see me here."

Pochettino has compared himself to a doctor and a teacher in recent weeks, but this time he took to construction to explain his slow progress.

"We have good people building the house, good architects," he continued. "We have the best company, architects, very creative and good - already proven. But when you want to build something, you need solid foundations, which are sometimes affected by the nature of the circumstances.

"You dig the hole, and there is water; it is not because of the company. An unexpected situation which delays the possibility to move quicker than you expected."

A key resource missing from Chelsea is their multitude of injured players and, even as Christopher Nkunku and Malo Gusto return from injury, Reece James, Robert Sanchez and Marc Cucurella have all been sent to the treatment room.

He said: "You ask me about Nkunku; it is like a new signing because we didn’t use him except for pre-season. Romeo Lavia will be fit in maybe one week or 10 days.

"These are two players who still haven’t made their debuts. Chilly [Ben Chilwell] and [Wesley] Fofana, who maybe needs more time, but we need two, three or four more players - [they are either] not making their debuts with us or are key players for us.

"I was talking, I am never going to ask, you know me from Tottenham and Southampton, and it is always about helping all the project. We are in a project and we have signed players and have a new squad but [we have had] a list injuries since the beginning and it was massive.

"We didn’t come from a consistent and solid season because it is a new season, new project and new team. Of course, when you receive all these hits against you, then it is not easy. But step by step, we will arrive. In this type of project, four or five months is nothing. The situation internally, we will fix it. We will fix it."
