The French international midfielder looks to be edging closer to a Santiago Bernabeu exit after being omitted from the club's provisional touring party by coach Jose Mourinho
According to the Washington Post, Madrid coach Jose Mourinho has named a 25-man group for the tour, which kicks off the club's preparations for the upcoming season. Diarra's initial exclusion could signal the end of his time at the Santiago Bernabeu.
Diarra has previously expressed his wish to remain at Real Madrid but in the light of stiff competition for places in the midfield and the recent signing of Nuri Sahin from Borussia Dortmund, Mourinho may have forced the player's hand.
Premier League champions Manchester United and Serie A giants Juventus have previously been mentioned as having an interest in the 26-year old, who has won 28 caps for France since his international debut in 2007.
The former Arsenal and Chelsea midfielder, who joined Madrid from Portsmouth back in 2009, is not the only notable omission - Royston Drenthe and Pedro Leon will also be left behind in Spain.
