selling Borini is a mistake, he can be a lifelong solid-to-amazing backup for a PL and CL winning side, and he doesn't complain much about playing, and turns into a good tutor.
Hughes is a fantastic buy for an attacking CM or CAM spot.
(LFC Marshall's newest update)
Liverpool need a solid young prospect and an established starter at CB.
Zouma/Papadopolous are great guys there.
Bruno Martins Indi can be fantastic and is cheaper.
A starting winger is also in order.
Oxlade-Chamberlain is a solid player who could develop alongside Sterling.
Some cover in the center of midfield.
Kondgobia is a great buy. Lots of young solid CMs. Nathaniel Chalobah is pretty fantastic as a DLP or BWM if you give him a year or more to develop.
