Dozy Mmobuosi is prospective new owner of Sheffield United - Paul Heckingbottom has his say

And after a transfer window and embargo which could have sidetracked his team, he is happy to be kept out of the loop and left to concentrate on football.

Unconfirmed stories emerged on Thursday that Nigerian billionaire Dozy Mmobuosi is close to a £90m takeover of the Championship club having begun taking the Football League's owners and director's test.

Mmobuosi is chief executive and co-founder of what started out as a publishing company but now specialises in the telecommunications, remittance, healthcare and agriculture sectors. Tingo International Holdings is valued at £7bn.

When the Blades manager spoke to the media on Thursday afternoon reports of the takeover had emerged but Mmobuosi's name was still to come out.

"It's not for me to talk about and I don't know anything," he said of the possible takeover.

"I haven't got a clue who he is, she is, and I don't want to know. If people thought I should be involved in it, I would. My focus is the players and the staff here and trying to get results."

The Blades remain under a transfer embargo for failing to pay instalments due on previous transfers but the threat of key players being sold to lift it ended when the transfer window shut on Tuesday. Clubs can no longer buy or sell players this season.

Heckingbottom is "thankful and grateful" for the outcome.

"In a difficult situation I think we've got the best of it," he reflected. "It was important for me not to make a bad situation worse and I'm pleased and grateful we've kept the players.

"They (Sander Berge and Iliman Ndiaye) could have been sold but they weren't."​​​​​​

"My job and the staff's job was to be ready for whatever panned out. Luckily I got the one I wanted, now it becomes irrelevant and we'll start planning for the future and that's for the club to pay the outstanding balance, whatever it is, to lift the embargo.

"It's not a distraction. It's not. If anything I think the outcome reinforces our intent and our desire that we want to achieve what we set out to and it gives us the best possible chance.

"There were no guarantees and we had to prepare for every eventuality but everyone was working towards the same thing and we've got that.

"It was a big thing for me in the window because we wanted to know and it changes by the hour. Now, there's nothing, so I'm going to forget about it, leave it to other people and we can get on with the football now."

Daniel Jebbison will be suspended for Saturday's Championship game at Rotherham United after his red card at Wrexham. The Blades had considered an appeal but with no conclusive video evidence did not.

James McAtee went off injured at the Racecourse Ground, but is expected to be fit to face the Millers.

"I think he'll be all right," said Heckingbottom. "He's trained today (Thursday) although we've looked after him a little bit.

"Ciaran (Clark) and Flecky (John Fleck) are back training with us. Ciaran's fine, he's trained, but only a couple of days,

"We know he's a long way away from where he wants to be.

"Flecky's been able to do a lot more physical work but it's getting him introduced to contact."
