Ajax coach John van 't Schip is delighted landing former Liverpool captain Jordan Henderson.
Henderson joins Ajax after five months with Al-Ettifaq of the Saudi Pro League.
Van t' Schip said: "We wanted an experienced midfielder with leadership qualities.
"Partially due to injuries in the team, we were looking for someone who could step in immediately. Jordan Henderson is that type of player.
"His arrival means a huge enhancement for our squad. Both on and off the pitch, a football player of this calibre is important for our many young players.
"He's an English international player and has won the Champions League and many other prizes with Liverpool. I am happy he's here, and I think it's very good for our club."
