The 22 year old was named in Fabio Capello's initial 30 strong party which will be trimmed down to a final 23 on June 1.
The Liverpool skipper said: "Adam has looked fantastic in training. He is a typical left-winger, he gets good crosses into the box, and is exciting on the ball.
"We will have to wait and see what players Fabio goes with in the final 23.
"But I am sure Adam has got a fantastic chance of going to the World Cup because he is a very talented player."
