I said it when we first signed him that he would evolve into a better midfield player than winger or forward due to his fluidity on the ball , being two footed he can change the direction of attack swiftly combined with when the team are clearing out of defence he can receive the ball on either side and not be phased to enable a counter attack to develop much more quickly quicker and before the opposition sets themselves, one criticism I always had on Henderson is I think he is a fantastic player however very linear - plays the way he is facing 80% of the time , extremely effective but linear ,where Lallana can play in a much more multi dimensional capacity , together they make the midfield and the team a much more potent force.
Quickly has become one of my favorite players.
