The Brazilian winger is set to leave Nou Camp, having only arrived in the summer transfer window. The Guardian are reporting that Spurs may bring Malcom on loan from Barcelona, who is also a reported target for fellow Premier League side, Chelsea.#2 Barcelona linked with Chelsea striker Olivier GiroudOlivier GiroudBarcelona are keen on adding a backup striker to Luis Suarez, and have been linked with several strikers recently, which includes the likes of Alvaro Morata, Fernando Llorente, and Javier Hernandez.The latest to be linked with a move to Barcelona is Chelsea's Olivier Giroud, as per Spain's Sport.
