Crystal Palace boss Sam Allardyce believes having games on transfer deadline day is a huge distraction for players and managers.
The comments came after the Eagles' 2-0 victory over Bournemouth at the Vitality Stadium, with Allardyce securing three points for the first time since joining the club, but the ex-England manager was less than happy with how the fixtures had fallen.
Palace announced the signing of Luka Milivojevic on a three-and-a-half year deal after the final whistle but Allardyce had no idea what deals had been done during the game.
He said: "I think the hard bit is the distraction. I had a player asking me if he was up for sale so that is what you get when you get this God-forsaken window.
"You get players being told information which is not true. Sometimes it has some validity in it but sometimes when you have a big game like we did and a player asks this, that shows just how bad this window is and just how bad it is putting a game on the same day.
"Our job is hard enough but to make it even harder than it already is, I really don't accept.
"I think there should be some sensibility about the way they pick the fixtures but yet again they will probably ignore us like they do all the time and just carry on in their own way."
He added: "(Milivojevic) is going to bring great ability in both feet, really good passer.
"He loves the sitting midfielder role and along with his ability, he will hopefully be as good as he can very quickly.
"There is no guarantee but I am looking forward to working with him."
Allardyce joined the Eagles in December following the departure of Alan Pardew but had failed to win any of his opening five league matches
Second-half goals from Scott Dann and Christian Benteke were enough to secure the visitors the three points at the Vitality Stadium, with the result keeping them two points behind 17th-placed Swansea.
Allardyce said: "I think that win has been a long time coming for me. I think our work and efforts on and off the field are what our recovery is all about about.
"We have been asking the players to listen to slight changes to try and perform better.
"The game plan was played well today by the players and we were clinical in front of goal. We won comfortably in the end."
Bournemouth have failed to win a game in January and conceded at least two goals in six of their last seven home league fixtures and manager Eddie Howe believes his side need a confidence boost.
He said: "I believe in the squad. We are going through a difficult period, confidence levels have been knocked, the only way to improve is to work hard on the training ground.
"We had a lot of possession and we didn't do a lot with it. You could tell the confidence was knocked, there were lots of backwards passes, we need to build on it.
"The results have not been what we want, that is the reality, the players are human."
