Lee Jae-sung taking indirect swipes at the former manager

What kind of philosophy is Manager Moreno instilling in the players? Lee Jae-sung said, "He wants us to have as much possession as possible compared to the opponent. At the same time, I think his most prominent philosophy is trying to break down the attack through as many short passes as possible. Because he trusts the players, we need to find our confidence."
Lee Jae-sung added, "Since we haven't played that kind of football for a while, there are some awkward parts. However, the manager is setting up a game model and training to find those elements. As the players are engaging in this process, I think it will improve bit by bit."
[442.interview] What kind of football was the Moreno era trying to play... Lee Jae-sung: "He pursues a philosophy of long possession and attacking through short passes"
The players keep mentioning the former manager's tactics lol
Lee Jae-sung isn't usually this type of character; he must have been frustrated.
