The Argentina-born forward seems to whip up debate both on and off the pitch, and none more so than now, with the Owls struggling to turn around their form on a run of five matches without a win.
The Owls have one of the lowest chance conversion rates of just 13% across the Championship season and fired 24 shots at goal in their midweek 1-1 draw with Birmingham City.
In just half an hour on the pitch on Wednesday evening, Forestieri created more chances than anyone on either side, providing five opportunities for his side.
The 29-year-old also made more passes in the attacking third (21) than any of his team mates, aside from midfielders Barry Bannan (28) and Massimo Luongo (24), who both played 90 minutes.
Owls boss Garry Monk has suggested Forestieri will be given a chance in the coming weeks as a congested festive fixture list takes hold.
His contract is up in the summer and vice-captain Barry Bannan accused the former Italy youth international of not working hard enough to warrant a recall.
He said: “It's up to Fernando. We know the quality that he's got, but if you're not working hard in training and not working hard on the pitch, you're not going to play.
“So he needs to brush up on that side of things.
“Then, no doubt, he'll be one of the first names on the team sheet.”
