Real Madrid are plotting a double raid on Arsenal with summer bids for Alex Song and Thomas Vermaelen, reports the Daily Mail.
Jose Mourinho has already turned his attention to next season, just days after securing the La Liga title, which will be on its way to Santiago Bernabeu for the first time in four years.
Having established midfield as the area that needs strengthening, the Portuguese coach has set his sights on Song, whom he sees as the ideal man to marshal the Spanish giants in 2012-13.
Gunners boss Arsene Wenger will be desperate to keep hold of the 24-year-old Cameroonian international, now that the African ace has developed into an important figure at the Emirates Stadium.
Reported interest in Vermaelen will also unlikely be welcomed by the Frenchman, having worked hard to strengthen his defence with the blossoming central defensive partnership of the Belgian stopper and Laurent Koscielny.
With Robin van Persie set for talks over a new long-term contract to remain in north London this summer, it will be imperative that Arsenal keep hold of all their star players beyond the transfer window, and continue to add to their squad with a view to a stronger Premier League title push next season.
