His peers on the pitch rate the 36-year-old as pivotal to Whites chances of regaining Premier League status more than any other.
Parker's astute awareness in midfield is the reason he has 18 England caps in his trophy cabinet.
He holds Whites together with a combination of prompting and passing that seems effortless.
In fact, stats table say so far this season, his 91 per cent accuracy with balls to his own team-mates is 25 per cent better than the next player: Tom Cairney, and the August player of the month nominee is no slouch with the ball either.
Parker suffered ankle damage that limited appearances last season.
However, fully fit after a decent pre-season, the former Tottenham, West Ham, Newcastle and Chelsea player has played 16 times for Whites so far.
On great example of his influence on the side was in the 2-1 home defeat to neighbours QPR on November 1
Fulham were dominating play with the score at 1-1 when Parker went off after 78 minutes.
Cairney had already been replaced, and a game that should have been won saw Fulham somehow lose 2-1.
Maybe it’s true what they say about great players – they make it look easy.
Parker is all of that and more.
There was a time in the madcap regime of Felix Magath when Parker his hand in his pocket and paid £20,000 in fines incurred by two youngsters.
The injustice of the punishment went deep with a disaffected squad, but Parker’s human touch went a long way to cementing him in the hearts and minds of his team-mates.
Last season ex-Wolves Jamie O’Hara, no spring chicken, said when Parker spoke in the dressing room – everyone listened.
Current boss Slavisa Jokanovic said there’s a job for the captain at Fulham next season regardless of whether he’s a player or a coach.
By the way, if you missed seeing yourself at Brentford last Friday - the above video could see you cheering Whites and Parker to a fine 2-0 win.
