Lowe, the man who was Saints chairman when Lallana joined the club, believes the midfielder will succeed at Anfield.
He said of the £26 million Liverpool paid: "Yes it's a vast amount of money but that's all part of football now.
"Relative to some of the fees being paid for other players I think the purchase of Adam represents good value.
"Some of the other fees are ridiculous but Liverpool have got a very gifted player.
"Adam sees a pass and is fantastic on the ball. He's a very decent boy."
