Celtic manager Brendan Rodgers is optimistic that continued communication with the board can help avoid another frustrating transfer window.
Rodgers expressed dissatisfaction during the summer after missing out on key targets such as John McGinn, although Celtic broke their transfer record to keep loan signing Odsonne Edouard at Parkhead.
Another loan signing, Leicester's Filio Benkovic, has impressed in central defence arriving shortly before the deadline but Celtic were left with a striker shortage after Moussa Dembele departed at a late hour.
Both chief executive Peter Lawwell and Rodgers admitted they had their frustrations when quizzed at the club's annual general meeting on Wednesday, but the Celtic boss has put those behind him after his side moved top of the Ladbrokes Premiership before the winter break.
"It was a frustration and I think that was well-documented," he said ahead of Saturday's trip to face Hamilton.
"I'm not one that can hide it very well. I have to say I was not hiding it very well at all.
"So there was a natural frustration there because, of course as the manager and leader of the team, you want to continue pushing the team forward.
"But you come away and you review and reflect and what's great here about my relationship with the board, when you work so closely together it's only human that you don't always agree. That's natural, whether that's your work life or your social life.
"But what there is always between us is a huge respect, because there has been an incredible collective effort here on and off the pitch for us to be where we are now as a club.
"So that has to be sustained, and the way you do that is by communicating and talking and looking and planning forward.
"So, yeah, a frustrating period, but gradually we have worked our way through that and come out the other end in a really good position.
"But of course it's constant and in January we hope that we can improve the squad if players are available.
"January, in my experiences up here, is always an important window to strengthen. If we can do that, that will be the aim."
