Wenger admitted: "It was the most disturbed pre-season we have had since I have been here.
"We had the uncertainties about players going out â€” two big cases like Fabregas and Nasri â€” and then we had the problem of injuries as well.
"Then we had the fact that we could only complete the transfers very late â€” and then we had this big cloud of Udinese in the Champions League in our heads.
"We knew that the season would be played on that.
"Like in any company, you need everybody to be on board and focused.
"Fabregas and Nasri played completely well and respectfully, but they were not completely here."
