Liverpool are continuing to chase young signings.
Since taking over in October owners Fenway Sports Group have stressed the need to extract more value for money from the transfer market, with the focus particularly on younger players.
It is a policy which served them well in their ownership of baseball franchise Boston Red Sox and one they hope to extend to Anfield.
However, the £20million deal to buy England Under-21 international Henderson indicates the Americans' willingness to spend significant money when they feel it is worth it.
"You're seeing the desire to win and the desire to compete in the transfer market," said Billy Hogan, managing director of Fenway Sports Marketing, the group's commercial arm.
"We would expect to have a couple more additions as the summer progresses.
"Damien Comolli (director of football) and Kenny (Dalglish) have certainly been clear about the desire to add talent where they can."
Hogan told Bloomberg: "When the ownership group acquired the Red Sox 10 years ago, one of the focuses was to develop the youth and in particular our farm system.
"That ultimately is where the Red Sox have been able to compete by bringing in what we call homegrown talent: young and talented baseball players that were grown within our minor league system.
"That's certainly something that holds true across the organisations. We're always looking for young talent."
