A number of Fulham's first-team players are currently on loan deals, and despite the fate of the club already being sealed, Parker insisted his troops will remain focused.
“I'm a professional person and the players are as well, and they have a job to do," the Fulham boss said.
“They're employed by the football club, they have a job to do and they're in the biggest and the most spotlighted league in the world, bar none and every week you go out there that spotlight is shining on you.
“Whether you're relegated or not there's a pride and a professionalism that needs to come into place and that's my message first and foremost to the team.
“Of course like anything, these are the moments when you really see what people are made of and you see what certain traits people have in their character and it's normally during the tough times.
“I've seen that throughout this year with this group of players and they – at many times – have stood up to that and they've been strong in that and they've got traits that have been positive.
“But like I said you only really test someone's personality or traits or see that during adversity and now at this moment there can be a lot of excuses, there's a lot of reasons why maybe one or the other doesn't need to perform at a level, but the facts are they do."
