I don't class Dalglish as a striker or Suarez or Beardsley they were more playmakers who set up the strikers. The only reason Suarez is played in that role is due to Carroll's shortcomings in front of goal.
Dalglish and Beardsley you can class as second striker or forwards because they created and scored goals, Suarez I am afraid does'nt, he does create and cause havoc with his little turns and nutmegs but I see him more as a midfielder who can occasionaly play up front in an emergency, he misses far too many chances to be regarded as a forward for me.
