24 years old, at the club since he was 4.
Twenty years wrapped in cotton wool and told he's the best player ever. Twenty years following strict directions.
He's old beyond his time, and has probably become bored with the same daily routine. Perhaps (like a lot of fans) he's grown tired of Pep's (increasingly slower) retain/recycle football for the past 7/8 years.
It wouldn't be unreasonable to think that he enjoys his family life a lot more than football, watching his kids living the type of childhood he never really had.
Phil's development has stalled. He's still being given 'second fiddle' roles by Pep, and there's no indication of Pep rebuilding the team around him as we all expected.
There's still a great player in there. He just needs a fresh opportunity.
