Liverpool believe they can still receive £30million for out-of-favour Mamadou Sakho before Thursday's transfer deadline.
Crystal Palace and Leicester City look primed to battle it out, though West Brom are also hovering with Jonny Evans likely to depart.
The Eagles remain favourites after his successful loan spell, meaning the Reds can secure a sizeable profit on the French star, according to the Liverpool Echo.
However, Sakho's preference is to return to Selhurst Park where he enjoyed a successful loan spell in the second half of last season. His performances for the Eagles helped them pull away from the relegation zone.
With three top-flight clubs in the race, Liverpool intend to hold out for the £30million asking price they set at the start of the summer.

Palace were reluctant to bid that high but they have been forced to reassess after a disastrous start to the campaign.
Sakho hasn't played for the Reds since April 2016. His relationship with Jurgen Klopp broke down after he angered the manager with repeated breaches of club discipline.
