Someone who is well-placed to talk about a striker's expectations is Aldridge - one of the most prolific goal-scorers in the history of English football.In his column for the Liverpool Echo, he said: "During my playing days, people used to talk of needing a month or so to get up to match fitness over the summer and Isak will have had about six or seven weeks by the time Manchester United arrive at Anfield on Sunday afternoon."OK, the games he has been involved in for Liverpool so far have all had something riding on them because they were not friendly fixtures, but it feels like the international break for Sweden will have helped him get fitter at club level."Now is the time for him to deliver.
