If Barnes goes back to Leicester that leaves us with quite a gap to fill. Morrison when he is at his best, can play a similar role, but when he last played he seemed a bit off the pace.
Hoolihan is a creative intelligent player, but at 36 you can't expect him to make too many bursts forward. What we would need is a player with a change of pace who can take the ball past players from midfield. Maybe the best replacement would be Harper?
