Then a Watford player, Forestieri had a straight choice between Wednesday and Leeds United in August last year, but eventually plumped for the Owls on Faurlin's advice.
"Alejandro is a close friend of mine and before I signed for Wednesday, I spoke to him and asked him what his thoughts were and should I come here," the Italian told the Star.
"He said: 'Don't think and go to sign.' I want to say thank you to him because he pushed me to sign for Wednesday."
Wednesday paid a reported £3 million for Forestieri, their highest expenditure since Puff Daddy & Faith Evans were at No.1 in the UK singles chart with 'I'll Be Missing You', and the 26-year-old has been worth every penny.
In April he became the first Owls player to exceed 14 goals in a second-tier season since David Hirst in the 1990-91 campaign, and he is widely regarded as the catalyst of the club's bid for promotion.
Despite playing for Italy at various youth levels, Forestieri, like Faurlin, was born and raised in the Argentine city, Rosario.
Earlier this season, Forestieri tweeted the 29-year-old after the pair were both named in Who Scored's Championship team of the week.
"Happy for you," wrote the Owls number 45. "I hope one day we play on the same team!!!"
And, while still a long shot, his wish moved closer to fruition on Monday, when Faurlin was released by QPR after seven seasons at Loftus Road.
