Birmingham City boss Alex McLeish says David Gold and David Sullivan would be good owners of West Ham United.
The former Brum co-owners have reportedly made an offer for West Ham.
The duo ran a tight financial ship but McLeish felt comfortable working within certain boundaries.
He said: "Every manager would like to have money available but I had no real problems with the previous board.
"I knew the parameters and as long as you have got that in black and white, then you can get on with it.
"We had success, getting back to the Premier League at the first time of asking, so it was a good partnership."
