Barcelona are monitoring three midfielders ahead of the January transfer window - including Arsenal's Jack Wilshere according to El Mundo Deportivo.
Barcelona lost their 100% record in La Liga on Saturday as they drew 0-0 against Osasuna without Lionel Messi.
According to El Mundo Deportivo, the Catalan club are wary that they are short in midfield following the departure of Thiago Alcantara over the summer, and with Xavi and Andres Iniesta not getting any younger, are looking at alternatives.
The paper claim that on their list of potential midfield signings is Arsenal's Jack Wilshere, Borussia Dortmund's Ilkay Gundogan and Koke of Atletico Madrid.
Wilshere has endured a tough time of it recently and watched on from the bench as England sealed their World Cup qualification last week, but bounced back with a brilliant goal in Arsenal's 4-1 win over Norwich on Saturday.
El Mundo Deportivo claim Barcelona scouts ran the rule over Wilshere at the Emirates Stadium before they landed Alex Song in 2012.
The Catalan club were reportedly impressed with Wilshere's technique, although whether they would be able to prise him away from the Gunners given that he penned a new deal in December is another matter.
Gundogan appears to be the most likely option of the three having stalled on signing a new deal with Borussia Dortmund - although Manchester United's reported interest may complicate matters.
Koke - who has been linked with a move to Manchester United amidst reports that the Old Trafford based club could make a £16 million offer - is an option and may be viable after Barcelona allowed David Villa to move to the Vicente Calderon on the cheap in the summer window.
