The Reds have agreed the fee with QPR for the France international striker, who spent last season on loan at Newcastle, and the deal had been expected to be completed on Thursday.

Remy has already passed a medical with Liverpool and has agreed a four-year deal, but it would seem as if the move will not be concluded until next week.
