Bolton are believed to be ready to make a late move for Espanyol midfielder Ivan De la Pena.
The 30-year-old is out of contract at the end of the season, although he is closing on agreeing terms on a new deal.
However, Sam Allardyce is interested in taking the former Spanish international to The Reebok Stadium.
With contract negotiations still to be concluded, Bolton may attempt to lure De la Pena to England.
De la Pena has previously stated a desire to move to the Premiership and may be offered the chance with The Trotters.
Racing Santander are also keen to sign the midfielder, although Espanyol remain favourites to secure his long-term future.
De la Pena is thought to be looking for assurances on his future by being offered a two-year deal.
