One player will who definitely not be going anywhere in a hurry is Fabian Delph, after the midfielder was ruled out for eight months with anterior cruciate knee ligament damage suffered in training.
"He puts his heart and soul into training," said O'Neill.
"He loves the football and he just turned away from a couple of players, someone came in to close him down and he has fallen awkwardly.
"He will recover from it. These things were career-threatening about a quarter of a century ago but nowadays players recover from them very well and just take it as a normal injury, albeit one that takes longer to recover from."
