Leeds United manager Neil Warnock is unhappy captain Robert Snodgrass did not return from international duty until the early hours on Thursday.
The Scotland international emerged off the bench in Wednesday's 1-1 draw with Slovenia and it was their travel plans that did not sit well with the Elland Road boss.
Warnock believes things should have been organised better so players would get a decent night's sleep and that their normal routines were not disrupted.
The former QPR boss has been working with his troops ahead of the visit of Championship leaders Southampton and he admits it has not been easy with players on international duty.
"Snods didn't get back until 4am this morning," Warnock told the club's official website.
"That's disappointing because surely they could have stayed over and organised themselves better so they don't disrupt peoples sleeping patterns like that.
"I'm not a fan of international friendlies, but people tell me the young players get something out of them, so I take that on board.
"It hasn't been the easiest week with players away and we've had one or two who haven't trained for one reason or another, but those that have been here have worked very hard."
