Eriksen was left out of Tottenham's FA Cup game at Southampton on Saturday, despite travelling to St Mary's, and is set to travel to Italy early next week for a medical.
His absence from the side who drew 1-1 at Southampton seems telling, but it has left Mourinho with a nasty taste.
"You can read what you want to read, I don't want to say anything," he said. "I just want to say that this situation shouldn't happen on the 25th of January.
"And it is not Tottenham's fault that on the 25th of January we are in the situation.
"The only thing I can say is Eriksen, since I arrive, he is behaving in a very, very professional way, with me and the team.
"Tottenham is the last one to blame for this situation, but to be on the 25th of January in a situation like this is not nice."
