They probably won't get better by not playing. Liverpool football club act in the its own best interests not individual players. If there not good enough, there not good enough. I'm not claiming to be some know-it-all coach, I'm just pointing out the blindingly obvious. You can't just stick in underperforming or youth players in the hope that they improve and still finish in the top 4. The fact that Rodgers, who is actually a coach, has left the likes of Borini and Lambert out suggests they're not good enough. And as for youth players, I can probably count the amount of youth players that have come through and been good enough for the first team in the last decade on one hand. Its fans like you who always want to see new players come in and tried out and 9 times out of 10 they're not good enough. I bet you wanted to see Pacheco, Suso, Ince given a chance. Everyone's entitled to an opinion, except you seem to be more interested in criticising other peoples's rather than having one of your own.
I don't believe that Lambert, Borini and Balotelli are all so bad that it's better to put out a team without any strikers at all. It's like saying that Mignolet is not good enough so we won't player a keeper... or we'll stick Lallana in goal.
Lambert played well for Southampton in the league. Borini was BR signing who did well enough at Sunderland to attract a £14m bid. Balotelli is an international who has won the premier league. None of them maybe good enough for the long term but I just can't understand how at least one of these couldn't do a job for us in the short term.
