Following the defeat to AEK in the Greek derby, Hasi will be axed today by Olympiakos as the Greek champions have already started searching his replacement.
Gustavo Poyet has been linked with the vacancy, however, Takis Lemonis seems to be the favourite to return in charge.
Lemonis lead Olympiakos to their 7th title in a row last season in his third managerial spell at Olympiakos but his deal was not renewed as Olympiakos hired Hasi as a manager before the pre-season.
Now, Lemonis is very likely to return to Olympiakos for a forth time in his managerial career as he is considered as the best candidate at the time being.
