As if to emphasise

"And that’s probably top spot boxed off for PSG. A great ball from Marco Verratti picks out Edinson Cavani in the box, who flicks a delicate one just over the first defender and Mbappe does well to get some power on the header. As if to emphasise that they want the win in this one, PSG’s players grab the ball from the net and sprint back to the centre circle like they’re 3-0 down in the final." (The Guardian live sport report.)

Is As if to emphasise that they want the win in this one a non-finite subordinate clause with the implied subject PSG's players and the direct object (a content clause) that they want the win?
