Real Madrid are reportedly considering selling Argentinean winger Angel di Maria for in excess of £47m [€60m] to fund a move for Monaco's Radamel Falcao.
Paris Saint-Germain have reportedly been keen on signing Di Maria, but have failed to meet the valuation set by Real.
Falcao could cost the Champions League winners in the region of £30m, but they will wait towards the end of the transfer window to see if the Colombian striker recovers from his knee injury.
Real have already been busy this summer, with the purchases of Bayern Munich's Toni Kroos and Monaco's James Rodriguez.
