Dani Osvaldo and Gary Medel should have their Inter medicals next week after deals with Southampton and Cardiff City.
According to Sky Sport Italia, Osvaldo will fly in tomorrow morning and have his medical on Tuesday.
The delay is so that Southampton can finalise the missing details in the exchange of loans with Saphir Taider and Ezequiel Schelotto.
The same sources claim Medel is expected in Milan on Wednesday, as President Erick Thohir and Cardiff owner Vincent Tan are discussing the transfer personally.
It is believed the clubs will agree to a transfer fee of €8m-9m plus a bonus for Champions League qualification.
Cardiff manager Ole Gunnar Solskjaer confessed "we expect an announcement to be made soon."
