Arsenal full-back Nacho Monreal is reportedly a target for a trio of La Liga sides, with Valencia among those hoping to lure the Spanish international back home in January.
Monreal has found first-team opportunities difficult to come early in the campaign, with Kieran Gibbs staying fit and in form to nail down a regular starting berth at left-back.
The 27-year-old may fear for his World Cup place and three Spanish clubs are poised to take advantage, according to The Mirror, with Granada and Real Sociedad also said to be monitoring his situation closely.
Gunners boss Arsene Wenger is believed to be adamant that Monreal is not for sale when the transfer window reopens in January 2014 after using the former Malaga mainstay 16 times so far this season.
Spain boss Vicente del Bosque has kept Monreal in his squad despite his reduced playing time since moving to the Premier League, including a call-up to a friendly double-header in Africa last week.
