The forward has had a fine season for Sheffield Wednesday so far.
Sheffield Wednesday boss Carlos Carvalhal has admitted his surprise at how good Fernando Forestieri actually is, and claimed that he is currently one of the best players in the Championship, the Yorkshire Post reports.
The 25-year-old arrived at Hillsborough towards the end of the summer, having enjoyed a mixed time at Watford, and has been instrumental in the Owls' strong form that has taken them to the brink of the play-off places.
And Carvalhal explained that he now sees no reason why the forward cannot become an even better player.
"I believe he is a better player now than in the past. He is one of the best players in the competition, I'm absolutely sure," he told the Yorkshire Post.
"More than scoring goals, he is a team worker and he is a very, very important player'.
Forestieri's move to Wednesday has presented him with the opportunity to showcase his talents, having often been more of a rotational option with the Hornets. The Argentinian made 66 league appearances for the Vicarage Road outfit after his loan deal was made permanent in 2013, and helped the club earn promotion to the Premier League last term, scoring five goals along the way.
However, just under half of his appearances for the club saw him start on the bench, which made it much less surprising that he was happy to move on while many of his former teammates continued to enjoy a run in the top flight.
But Watford's loss has been Carvalhal's gain this season. The playmaker's 10 goals in just 18 appearances makes him the division's third highest scorer, behind Fulham's Ross McCormack and Andre Gray of Burnley, who both have 13 strikes to their names.
And having not been able to enjoy a shot at the Premier League with Watford, Forestieri will be hoping that a continuation of his excellent form will earn him his second promotion in as many years.
