Collymore has been impressed with the work carried out by manager Rodgers - including developing young players into first-team members - since his appointment last summer.
"But he's getting together a very good young team, players like Andre Wisdom, Raheem Sterling and Philippe Coutinho. The aims and ambitions for Liverpool this season is to try to get into that top four.
"Brendan Rodgers has to do what he does best - which is take young players, develop them, coach them and work with them every single day.
"But I do see Liverpool, in the next five years, being successful in England and Europe once again."
