Liverpool have opened talks with Barcelona over the possible transfer of the defender Martín Montoya in January.

The Spain Under-21 international, who can operate in both full-back positions, is out of contract at the end of this season and his availability has alerted leading clubs throughout Europe. The 22-year-old and his agent have both claimed recently that he hopes to sign a contract extension with the Spanish champions but Liverpool are exploring the prospect of a permanent deal in January.

Montoya's opportunities have been restricted at Camp Nou by the excellence of the right-back Dani Alves but talks have taken place over a contract renewal. That has not deterred Liverpool, however, and their managing director, Ian Ayre, met Barcelona officials in Catalunya on Thursday to discuss a possible transfer fee.

Brendan Rodgers, the Liverpool manager, is keen to strengthen competition at full-back despite signing Aly Cissokho on loan in August and Jon Flanagan's impressive performance on the left at Everton on Saturday.
