Jon Brady says his main focus is on Saturday's game after being asked about the players in his squad who are out of contract in the summer.
“We want to retain players who will make a difference for us,” he said.
“We are speaking to players all the time and I’m ambitious to keep hold of those players who make a difference for us.
“We’ve stepped up a level and we’ve seen how those players have performed at this level, and it should also be said that as a club, we will be an attractive proposition to a player.
“Contract negotiations is an ongoing process and its never that easy, sometimes it can be a long drawn out process as it can be trying to recruit players but I think we are in a good place and our full focus is on Saturday's game with Charlton.”
