I disagree.
Completing transfers is a complex affair and the market so dynamic that it's hard to get business done to a set timetable. In a perfect world you get your deals done early in the window, but it doesn't always work out.
I do agree though that players coming and going is disruptive, but not necessarily down to '' poor planning ''.
I think the main contributors to the poor start were actually ;
* having six players involved in internationals in the summer in which their respective countries were involved until the very end ( England and Colombia )
* Andersen and Mateta were also on international duty - culminating in a less than effective pre season.
* we missed Olise ! Eze in particular has suffered by his absence
* injuries to Wharton and Eze
Players such as Lerma and Munoz have started to rediscover their form. The back three are now functioning well as a unit. Hughes has stepped his game up and Henderson has started to show why he commanded the fee paid for him. Additionally Sarr is starting to show why Dougie was so keen on him. So progress although slow, is now being made.
I think Palace will dip into the transfer market in January, and hopefully give the squad more strength in depth.
