Rodgers – who landed the midfielder from his old club Swansea – has likened Allen, 22, to Barcelona star Xavi.
That leaves a lot for Allen to live up to but Rogers insisted: “I would have paid many millions more for this kid. He’s unique in that he’s a British player who is incredible on the ball.
“His body work is very intelligent and for a 22-year-old it’s frightening. He’s incredible.”
