Brown told The Sun: "We’ve been friends forever.
"So he has always seen the sort of dedication I have and, for the last couple of years, he’s just been helping me and looking after me, sponsoring me and stuff.
"I massively appreciate it. It’s mint that he’s in a position to be able to do that for me because he’s just a normal lad.
"We played footy, liked going fishing, everything we liked to do back then, we still do now, but it has to be a bit more ‘behind-closed-doors’."
When asked who was more successful on their fishing trips, Brown added: "If I have to be honest. It’s him. But if I gave it a bit more time, it would be me! But Phil is just fishing crazy, fishing crazy.
"And he gives it everything, like you said, he’s not out, falling out of nightclubs.
"If he’s doing something, it’s probably fishing, which is not detrimental to his sport.
"He’s a good lad, he’s just a normal lad who happens to have millions of cameras on him.”
