Liverpool will step up their interest in Manchester City's Joey Barton and Nottingham Forest defender Michael Dawson at the end of the season.
Merseyside-born Barton has only 12 months left on his contract and has yet to agree a new deal.
Forest also face a fight to hold on to talented 20-year-old Dawson, who is a long-time target for top clubs.
And BBC Sport understands Liverpool manager Gerard Houllier is poised to lead the chase for the pair.
Liverpool are likely to have to pay around £3m for Barton, while Dawson is rated in the £5m bracket.
Barton is a close friend of Liverpool captain Steven Gerrard, and recently had a public disagreement with City manager Kevin Keegan after he was dropped.
Liverpool are also interested in Barton's team-mate Shaun Wright-Phillips, but will face a fight to land the winger after City's Premiership safety was assured.
Anfield boss Houllier will waste no time in re-shuffling his squad, although they are still favourites to clinch a place in the money-spinning Champions League.
Auxerre's Djibril Cisse will arrive in a £14m deal, while Liverpool striker Emile Heskey is expected to sign for Birmingham City shortly after the end of the season.
