Arsenal are preparing a raid on Barcelona as Arsene Wenger has now set his eyes on bringing forward Alexis Sanchez, defender Martin Montoya and former Gunners midfielder Alex Song to the Emirates at the end of the season, according to Tutto Mercato Web.

The north London club's manager is looking to strengthen his squad and the Frenchman will be handed a £70m transfer kitty to bring in new players this summer. Arsenal are in need of a striker and their long-term target David Villa is now set to sign a contract extension at Camp Nou.

With the Spanish international set for an extension, it is likely that Sanchez could leave the Spanish giants at the end of the season as he has failed to impress for Barcelona, since completing his move from Udinese in the summer of 2011.

The Chile international has failed to feature regularly for the La Liga leaders this season and has now fallen down the pecking order. Sanchez has started only 11 games and scored just two goals in the league this season. Liverpool and Italian champions Juventus are also interested in his services.

Song and Montoya, like Sanchez, have also failed to start regularly for the Spanish giants. The Cameroon international, who joined Barcelona from Arsenal last summer and has started just nine games, while the Spanish defender has made only five starts in the league this season.

The Gunners have failed to find a replacement for Song this season and has struggled in the defensive midfield position. The midfielder was impressive for Wenger last season and was recently linked with a return to the north London club. Song has already proved himself at the Emirates and his return could bring back the stability in Arsenal's midfield.

Meanwhile, French international Bacary Sagna is reportedly set to leave the Emirates at the end of the season, as Ligue 1 outfit Paris Saint-Germain are interested in bringing the defender back home, opening up a spot for Montoya.
