A.C. Milan want Carlos Tevez to take psychological tests if he is to complete a £25m move to the San Siro.
The Manchester City striker's representatives recently held talks with the Serie A club over a possible January move.
However, the Rossoneri believe that a player's mental well-being is important to their performance on the pitch and have required the Argentine to take the tests, according to the Daily Mail.
Tevez is currently in Argentina after he missed training without manager Roberto Mancini's permission.
