Part of the all-conquering Bradford Bulls side of the late 1990s, since stepping into the coaching arena, Forshaw has worked with Warrington and Wigan in Super League before switching to Union and helping beef up Irish province Connacht's defence.
But in joining the Sharks, Forshaw has arguably taken on the toughest challenge of his career.
Sale's porous defence has been one of their Achilles heels in recent seasons with the Sharks having the dubious honour of shipping more points than any other side in three of the last four Premiership campaigns.
But rather than be daunted by the challenge in front of him, Forshaw - who is working alongside director of rugby Steve Diamond, head coach Bryan
Redpath and Academy transition head Pete Anglesea, is revelling in it.
"I've been really impressed by the environment and the organisation," Forshaw declared.
"Although I've only been at the club a month or so, I've been able to come in and help put some systems and structures in place in regards to the contact area.I think it was really important to let the players know what I'm about and what they can expect from me in that area of the game.
"As regards the challenge of tightening up the defence, I've been in this position before.
"When I joined Connacht rugby three years ago they had finished bottom of the pile for three years in a row.
"The first year I was there we finished seventh in terms of tries conceded and eight in the table overall. In the second year we finished seventh so I've been in that position.
"I'll put in place what I think is right but ultimately it's going to take a lot of hard work and that's what I've said to the players - we've got to be organised.
"For me, it's all three key words: disciplines, decisions and detail in the contact area.
"Within that 50m area of your try line, if you don't get decisions and details right, the kickers of today will punish you as they don't miss
"And once you go nine or 12 points down in the Premiership it's very hard to get back."
"So I want us to become tradesmen in that area.
"After all, if you get a joiner in and he does a bad job, you won't employ him again will you?"
"You want someone whose detail and discipline is good and who you don't have to ring up a fortnight later if you door is hanging off and its the same with rugby."
And despite the Sharks' traumatic experience of last season when they had to mount a desperate rearguard battle to avoid relegation, Forshaw believes
the core components are in place for the club to challenge at the right end of the table this time round.
"I spoke to a few people before coming here including England and British Lions coach Andy Farrell, who is a good friend of mine, and Wales coach
Shaun Edwards and they said there is a good squad here at Sale," Forshaw added.
"Having seen it for myself I know they are right. I look around and I think we've got some grunt but we also need that belief.
"And we need to start well. I know from watching Sale last year that lose your first few games and you are playing catch-up.
"The Premiership this year is going to be so competitive and i think Newcastle will be fighting as they are a big club, Dean Ryan is at
Worcester and he will have big ideas.
"So it will be tough every week. But overall, I'm pretty confident as I think we've got a good squad here with some really experienced guys and a lot of good young players."
