Its expected that the Irishman will be among the big spenders in the January transfer window.
O’Neill said: “Do I like the transfer window? Not particularly.
“I think what it does do is point everyone into this supposed window of opportunity – and sometimes you are panicked into things.
“After January 31 a manager is not able to do anything until the end of the season. He has that in his mind.
“Before the system was okay. I am not a fan of this one – and I am not so sure many people are – but whilst it is in place, you can’t do anything about it.
“You are not going to change the transfer window this season but I am sure people will be lobbying to try and do something about it and hopefully that will be successful in the not too distant future. In this particular year, whilst the transfer window is there, you just get on with it.”
