Bolton Wanderers boss Owen Coyle admits they'll struggle to hold onto winger Lee Chung-yong.
Lee came off the bench to net their FA Cup winner against Birmingham City.
Coyle said: "The reason Chungy is not starting is that the kid has played for two years without any sort of a break.
"If I was to keep playing him week in and week out, come the end of March he would have nothing left in the tank. As a manager I have to be very conscious of that.
"If it means Lee sits on the bench, comes on as an impact player and then starts games here and there, to make sure come the end of the season he is still fresh for me, then that's what we will do.
"Lee will go on to play for one of the top clubs because he has everything in his locker. He has got a footballing intelligence that you can't give players.
"He has an unbelievable touch, he can take the ball in tight areas. He is great to have at the club."
