The Mali international has been tipped to leave Madrid for quite sometime now due to his frosty relationship with Coach Bernd Schuster.
Diarra has not been featuring too heavily recently, and at the weekend he only played the last 20 minutes in the 1-1 league draw at Mallorca.
Inter have identified the signing of a top-class centre midfielder as their priority in this summer's transfer market, and coach Roberto Mancini's first-choice is Diarra.
The feeling in both Spain and Italy is that Madrid will sell Diarra in the summer, and the player’s agent Frederic Guerra has admitted that his client likes Inter.
“We will see after the match with Barcelona on May 7,” said Guerra.
“He is not happy to play so little and this is a worrying situation.
“It is true that he likes Inter but there are also two other clubs from the Premiership that like him.”
Diarra joined Madrid from Lyon in the summer of 2006 for €26m, however he has never really hit top form in the Spanish capital.
