The 19-year old centre-half had a breakout season with the Lancashire club and has subsequently attracted interest from bigger clubs around England but Kean has warned that he may not be ready to depart Ewood Park just yet.
"I don't know if Phil would go straight into the team at a Champions League club," said Kean. "And he wants to play. He wants to be a central defender, where he is looking fantastic.
"He is also a supporter and it's great for the fans to see one of their own playing. He was outstanding at the end of the season.
"You always brace yourself for bids. We have had offers before for him and I'm sure there will be solid ones in again. He will move on some time, but I can see him being captain here first."
