Brady came through the system at United before moving onto the Tigers.
"He's a determined guy, he has served his apprenticeship at United, he has grown up a lot and can now make decisions for himself," said Phelan.
"You can see that the maturity is there. He made the move which was important for him at the time to get the correct club. He has took it really well, he has become more professional and it benefits him, Ireland and the club he is playing for."
