"I think we have improved in terms of wingers with Yossi and Ryan, but also if you look at Jermaine - he is in very good shape and playing really well," he told liverpoolfc.tv.
"I think maybe this will be an important part of our game this season, out wide.
"Sometimes last year we had players out there who prefered to be in a different position, like Luis Garcia, who liked playing as a second striker. Also, we missed Harry Kewell to injury. If he is fit we are looking very promising in these positions."
