Reports emerged claiming that the 20-year-old is earning £850 a week following his winning goal against Manchester United last weekend.
"Seeing what came out in the press after the game last week, obviously his agent has been a little bit busy by putting things out in the open," Clarke said in a press conference.
"I understand that it's an agent's job and that's what he has to do, but now is the time for everyone to be calm and focus on improving Saido as a player.
"It was a little bit naughty for the agent to put out the level of his wages and what he earns. It's not correct, but if Saido continues to do what he's doing, he'll be looked after here. No problem."
The Baggies are preparing to take on league leaders Arsenal this weekend.
