Bannan and Lee have formed an effective partnership at the heart of Wednesday’s midfield, with their energy and desire catching the eye.
And Forestieri says that the work-rate of his two teammates encourages the rest of Wednesday’s squad to give their all.
“I like Barry and he is a very important player for Sheffield Wednesday,” the Argentine attacker said. “When you play next to Barry and Kieran Lee, you follow them because they want to win and fight for the team.
“The coach wants the strikers to work hard so the midfielders and defenders follow us.”
Bannan’s future at Wednesday was actually in doubt, as he only signed a short term contract when he moved to Hillsborough from Crystal Palace.
However, the Scotland international is said to be on the verge of singing a new long-term deal, and Forestieri is delighted that the 26-year-old is sticking around.
“It’s great Barry is going to sign a new contract for here because he is a very important player," he added.
Forestieri has also impressed for Wednesday this season, after he signed from Watford in the summer transfer window.
The diminutive attacker has netted eight times in 16 matches, and he scored a brace in the Owls’ most recent 4-1 victory against Wolverhampton Wanderers.
That victory has lifted Carlos Carvalhal’s side into seventh place in the Championship table, and they are just one point outside the play off places.
