Nerazzurri CEO Giuseppe Marotta has confirmed the club’s decision after Inzaghi led the Italian club to the Champions League and Coppa Italia finals, the cup competition he led Inter to victory in last year.
“We never thought, not even for a second this year, of replacing Inzaghi,” he affirmed to Rai Italia.
“He has managed to strengthen his position thanks to the team’s performances, which are obviously the result of his guidance.
“His confirmation, speaking in percentage terms, is 100 per cent. He is and will be our coach again next year.”
