Sam Allardyce insists he has no problem making tough decisions and upsetting players at Newcastle.
The St James' Park boss believes that it is impossible to keep his entire squad happy, but insists it is up to each individual to deal with any disappointments.
The former Bolton manager is also prepared to speak to any player who feels hard done by and will not allow bad feeling to fester.
Allardyce told The Mirror: "Players at some stage will walk out of the training ground and they won't like me.
"Some players will be fine however you've dealt with them on that day. Whatever you've done, someone walks out of the training ground dissatisfied with you.
"It's all part of life as a manager because you have to make decisions some of the players don't like or don't agree with. They can come and discuss it like men and then get on with it.
"I wake up the next day and whatever's gone on has gone on. Basically most of the time it's the players fault not mine - they drop themselves."
And the Magpies manager has hinted he is already looking to bring in more new faces during the January transfer window when he expects to temporarily lose the services of four key players.
Striker Obafemi Martins, skipper Geremi and defenders Habib Beye and Abdoulaye Faye could all be required for African Cup of Nations duty in the New Year.
Allardyce added: "I lose four, but most of the country loses a similar amount these days.
"I think there's only Manchester United who do not have an African Nations player playing. Most of the other teams do.
"It's a difficult period. The January window is something for me to talk about with Chris (Mort), the chairman, and try to plan for that as soon as we can and see what comes about."
