And Mowbray will allow that part of the South Korean's game to flourish when the likes of N'Guemo return. Mowbray said: "When we get some players back that are not available at the moment, he will play further up the pitch.

"He can shoot, as we saw with one free-kick, and I'm looking forward to getting the balance of our team right when we get some players back."
