They probably pulled away from Higuain because they thought he became over-priced.

The precedent has been set if LFC don't want to sell, we just have to keep rejecting, and they will move on.

petrescu doesnt get it obviously.

by speaking to the player, offering him a deal that he is willing to accept and then failing to pay the going rate for him, makes them look like timewasters.
if they had made an acceptable bid in the first place, liverpool may have accepted it, making the exit of suarez much easier, preserving his loyalty bonus and allowing arsenal to negotiate with him smoother.

As it stands, they have insulted the club and even if they agree terms with suarez, they will have to significantly increase their bid to buy him.
