"You have to ask the agent and Inter because they know more than me," said Mourinho on Friday.
"If they are confident it is because they are ready to make us an offer, which didn't happen yet."
The 27 year old has started all four of Tottenham's games this month despite Mourinho saying the player is "not totally focused" because of the speculation surrounding his future.
"When I see people speaking, especially people with responsibilities, it makes me surprised," added the Portuguese, who succeeded Mauricio Pochettino as Spurs boss in November.
"He is trying to do his best and it is normal until 31 January his brain is not totally focused. It is a normal consequence of the situation.
"For a few matches people are saying he is playing his last game. Eriksen plays tomorrow."
