Why is liverpool buying subpar players to fill in their team?

[epere]

They traded their world class striker for average players?

At this rate, they will be back where they are few seasons back.

I don't think so.
Suarez is player out of control, and it's always risk play with him in the team.
Liverpool really needed urgently some good defense player and in this season they could find at least one (Lovren) so I think they made smart decision.
Any way, soon we will find out

Liverpool bought some great players! They received so much for L. Suarez, they invested a good chunk of the money wisely in good players.

Not sure why you say they buy average players.
