The Italian is the Championship side's top goalscorer this season.
The former Watford man is the club's leading goalscorer with 15 strikes in the Championship and has been a key part of the squad that will look to secure their spot in the play-off places this weekend.
And Loovens discussed how important the forward has been to the club's fortunes this season.
"Fernando is a very big player for us, not just with his goals but his work rate up front. He works very hard and gives the team an extra dimension," he told the Star.
As the centre-back suggests, the 26-year-old has not only been valuable in terms of scoring goals but also in creating them for his teammates.
Only Ross Wallace has managed to contribute more assists than the six that Forestieri has managed this season, and if they do go on to secure a top six spot, it will largely be thanks to his influence.
His ability to play up front or drop in slightly deeper in an attacking midfield role means that opponents are often unable to predict what they can expect from Forestieri. He is more than comfortable dropping into midfield to pick up the ball, before using his tremendous skill to create openings for himself or his teammates.
And Carlos Carvalhal will undoubtedly need him to be somewhere near his best if the Owls are to capitalise on their current position and secure promotion to the Premier League.
