Are you being dense on purpose? That was an interview from Rashford to Henry Winter... those were his own words, not some leak.
Its a bit silly to call out a club for years about culture and standards, we all have, when a manager comes in and sets standards... you are hurt because its Rashford who is suffering.
So a player saying he wants to leave doesn't devalue him but a manager saying he needs to meet standards does? where is the logic in that?
If he was serious about a new challenge, he would have got a move, he hasn't because of his wage demands, so it is quite clear, he is not interested in a football challenge. He wants to be paid to do the minimum.
