Ferguson criticised the midfielder's running style in his autobiography after admitting being interested in the player when he was at Sunderland.
The Scot wrote: “We noticed Henderson runs from his knees, with a straight back while the modern footballer runs with his hips. We thought his gait might cause him problems later in his career."
Henderson has since insisted the comments didn't affect him, and took it as a compliment that one of the most decorated managers in the game was actually interested in him - but in part it may have helped his fans, team-mates and manager big him up - as Brendan Rodgers launched a staunch defence of his player in the fallout from the book's release.
The 24-year-old is quoted in the Liverpool Echo, saying: “To be honest I took it as a compliment that someone like that was looking to buy me.
“It didn’t really affect me, I wasn’t really bothered about it.
“But him saying that probably did get everyone behind me, although I think performances do that too.
“When you’re playing well the fans can see you’re giving everything and will get behind you. Every time I go out I give everything and they can see that.”
Henderson still has some improvement left in him, but last season showed how valuable a member of the side he has become.
There were several critics of the man from Sunderland but there were some terrific displays last season that it was hard to argue against him being the best English midfielder to play in the Premier League last season, and was duly awarded his place in the World Cup squad.
