That because those two are much younget players who have both spent last than 2 years here.
Stop with the "Poor old Jack" , "Jack is a victim" narrative. It's nonsense. No other player has enjoyed the privileges that Jack has since he came here, Sterling, Palmer, Jesus, the list goes on. Whenever any player defies Pep's instructions or think they should play more, Pep immediately moves them out to avoid discord in the team.
How many times has Jack completely done things against the interest of the team only to get a slap on the wrist? Drunk driving, being wasted on the tour bus, spending the entire end of season making a fool of himself, returning completely out of shape.
Any other player would have had the fans turn on him. Cut the fucking nonsense. If anything, Jack is protected like some fucking golden egg and going by what he contributes to the team, it shouldn't be that way.
