He could get a better deal if he waited it out but I'm afraid his stock will fall more if he decided to go through with it and turn down Inter's offer, with his current situation in the team we might see him less likely in the field. Also Inter Milan is the only team who seriously court him during this January transfer window and Tottenham cannot afford to pass up an offer for him. From what I have been reading his original 8.5 million pound asking price got turned down and Inter countered it at 6.5 million pounds and I think Eriksen will be accepting it before this weekend.
