The Inter manager is unsure if the Croatian will remain at San Siro amid heavy reported interest from the Red Devils
Luciano Spalletti wants to keep Ivan Perisic but does not know if Inter will be able to ward off interest in the star forward.
The sought-after Croatia international produced an impressive performance in the Nerazzurri's 2-0 win over Bayern Munich in the International Champions Cup, providing a superb cross for the second of Eder's two goals.
Perisic has been heavily linked with a move to Manchester United after scoring 11 goals in Serie A last season as Inter failed to qualify for European competition.
