Del Piero to face Berisha-less Brisbane
"We'll make a decision most probably tomorrow as to whether they'll be available."
Del Piero missed the sides 1-0 loss at Wellington last weekend due to lower back tightness after having been unable to return for the second half of the club's unconvincing 2-1 win over Melbourne Heart the week before.
Emerton, who made his return from several weeks on the sideline with a leg injury against the Heart, also failed to back up against the Phoenix, leaving Farina short of attacking options.
"I think we let ourselves down more so in the final third, made some wrong decisions, bad passes and then got caught on the counter so we've look at it and hopefully we get better," continued the coach.
It was the third match 39-year-old Del Piero has missed this season. He has also failed to complete three other games through injury this season.
Yet Farina refuses to concede the continued absence of his star performer is causing him a headache.
"No, it's not frustrating, it's not a distraction, it's football. It's life at football clubs," he said.
"We're not the only ones that go through it so it's just part and parcel of what we do."
Brisbane go into the clash coming off four wins in the last five – their only loss being a shock 2-0 defeat by Newcastle last Friday - and will be deserved favourite to take all three point away from Allianz stadium.
And Farina, for one, knows what his side is up against and what he wants from the cluster of festive matches.
"They're a very mobile side and they have players that can hurt you," continued Farina.
"Thomas Broich is arguably one of the best, if not the best, player in the league in the last two or three years so you combine all those things together and you've got a formidable side.
"I think if you want to be pushing to stay up the top now is an important time for everyone to keep collecting points and we're no different from the rest."
