New Wigan Athletic boss Steve Bruce is keeping his plans of reshaping the club's backroom staff to his chest.
"I'm hoping that I can make some additions to the backroom staff by the end of the week.
"Eric Black is still in work at Birmingham, but I'm hoping to bring in a couple of new faces."
Bruce added: "I was extremely impressed with the way they went about their job on Saturday (in their 2-0 loss to Arsenal). I know it's going to be difficult but my job is to try and give the whole place a lift. I'm very confident of staying in the Premier League."
