Warnock has fallen out of favour under Gerard Houllier at Villa Park and is considering an opportunity to solve Liverpool's left-back problem by rejoining them for the rest of the season.

While Houllier also likes Wigan striker Hugo Rodallega, his main target at the DW Stadium is attacking Honduran left back Figueroa.
Wigan boss Roberto Martinez has tried to play down Villa's interest in two of his leading lights but faces an uphill task preventing Figueroa heading for the Midlands later this month.
Houllier, who is close to finalising a £6million deal for Lyon's Jean Makoun, is also lining up Montpellier's Bosnian centre half Emir Spahic.
The 30- year-old was a summer target for Arsenal but could join Villa next week in a £5m deal.
