Eriksen started on the bench for their clash with Lazio on Sunday night.
Marotta said, “Eriksen needs time to settle in, but games last 95 minutes nowadays and everyone will be required to give their contribution. It's up to Antonio Conte to choose which players are in the best condition to start and who can be useful off the bench."
Marotta also insists there's no thoughts of Lautaro Martinez leaving.
“Lautaro is improving, he is a very young lad who I think is above all eager to wear this glorious jersey and grow professionally. As I always say, players only leave Inter when they point towards that exit."
