"It's the first time we have a young Englishman who, having scored a hat-trick against Croatia, will be faced with the same issues we faced with Ryan," Ferguson told Sky Sports News.
"Everyone will want a piece of him, agents will fall over themselves to get to the boy.
"What he requires is one strong manager and Arsenal will give him that, without question.
"The boy must also have the understanding that what is being done for him is for his own good.
"Ryan had the understanding and the intelligence to deal with that, he didn't want the showbiz thing, he didn't want to give interviews, he just wanted to be a footballer and these will be important issues for Walcott, because he's got a talent."
