"He didn’t play for the first four months [after joining from Spartak Moscow] because he needed to adapt to Italian football, but once he was in the team he never came out again. Maksimovic was a very important player for us, a defender with great potential.”“We’ve never seen the real Maksimovic at Napoli, not least because he was used to playing in a three-man defence with us. If he joined Inter, he would be a very important reinforcement for [former Inter manager Antonio] Conte’s 3-5-2 system and he has a lot of character and pride. He would have a real point to prove so I think he’d be a great signing.”However, Conte left the club in May and the targets for the San Siro side have since changed.
