Bolton have rekindled their interest in Spanish defender Cesar with Sam Allardyce fearing the possible departure of Tal Ben Haim.
The Trotters boss has admitted that the Israeli international could yet depart the Reebok Stadium before the close of the transfer window with Chelsea tipped to push through a late deal.
As a result, Allardyce is scouring Europe for a replacement and has been linked with a number of players, including Paris Saint Germain's David Rozehnal.
It appears, though, he has now turned to long-time target Cesar, a centre-back he has been pursuing for over 12 months.
The 29-year-old is currently on the books of Primera strugglers Levante - a side he opted to join over Bolton in the summer.
However, he finds himself out of favour at the Valencia-based outfit and has been informed that he does not feature in the plans of new boss Abel Resino who replaced Juan Ramon Lopez Caro earlier this month.
The stopper missed Levante's 4-2 defeat by Sevilla at the weekend as he was reportedly negotiating a switch to Bolton and Spanish sources claim he will meet Levante officials on Monday in a bid to ease his departure from the club.
The Spaniards are thought to want around é¼1.5million (£1million) for the former Deportivo La Coruna man and that could represent shrewd business for Allardyce if Ben Haim does ultimately depart.
Meanwhile, Levante will move for Malaga striker, and former Bolton loanee, Salva Ballesta if Cesar does leave to free up a place in their squad.
