Sunderland boss Gus Poyet is unlikely to stand in the way of Ji Dong-won's move away next month.
Borussia Dortmund are closing in on the South Korea international.
Poyet conceded: “He’s a very good player, but I need to find the opportunity to say to him: ‘Here you go. Don’t try to think too much about how we’re playing, just go out there and play’.
“But I don’t know how to play him because that’s what he needs.”
