He admits the fixed transfer window model adopted in recent seasons has its drawbacks.
"I think you get used to it. I am not quite sure what the best system is now," he said.
"Do we go back to the old system where you could perform transfers at any time, and is that a system that favours the bigger clubs that are able at will to pick which ever players they want, or do you stick with the system we have now? Both structures have their positives and negatives. We have got used to this market now.
"I think the tough bit about this market is it can unsettle players, no doubt about that. I am not sure what the best system is, but this is how it is and we have to work around the best way we can."
