Aidy Boothroyd says his Northampton team will ignore the Edgar Davids "nonsense" when they travel to Barnet on Friday.
Champions League winner Davids joined the bottom-of-the-table Bees last week as head coach, working alongside manager Mark Robson - a move which Boothroyd admits he finds difficult to understand.
"It's a strange situation because I know Mark Robson," the Cobblers boss told BBC Radio Northampton. "I've known him for a very long time, we used to compete against each other when I was Peterborough's youth team coach and he was at Charlton.
"I know him very well and he's an excellent coach and I'm not sure of that situation. I believe it's a joint manager, which is difficult.
"I certainly wouldn't want to be a joint manager because I want to be in charge. It's going to be interesting to see how it pans out, we certainly won't get caught up in all that nonsense because we've got a football match to play and a football match to win.
"We won't be asking for shirts to be signed or anything like that, we'll just get on with the game."
