URGENT-Lukoil close to deal over Repsol - source

MADRID, Nov 21 (Reuters) - Russia's Lukoil (LKOH.MM) is close to a deal with Spanish builder Sacyr Vallehermoso (SVO.MC) and other shareholders to buy a 30 percent stake in oil company Repsol (REP.MC) but still needs to find financing for the deal, a source close to the talks said on Friday.

Lukoil could pay Sacyr 28 euros a share for its 20 percent of Repsol -- double Friday's closing price of 13.91 euros -- said the source.

The Russian company would buy another 10 percent from Spanish savings bank La Caixa, insurance company Mutua Madrilena, and Repinves, which is partly owned by La Caixa, the source said.

Lukoil declined to comment on reports of a deal, while Sacyr Vallehermoso referred to previous statements where the company has said no deal has been reached over its planned asset sales.
