There are reports Inter President Erick Thohir will release a statement cancelling the Mirko Vucinic move, but Fredy Guarin threatens to go on strike.
The transfer had been all but completed until Monday evening, when furious Nerazzurri fans attacked the club for what they saw as a bad deal.
According to the latest reports emanating from Milan, Guarin is at the Inter HQ demanding for the move to go through or he will go on strike.
It’s even reported the Colombian international midfielder called Honorary President Massimo Moratti to act as go-between with Thohir and plead his case.
Thohir only took over the club in November and is in Indonesia, but he is rumoured to be angry with his directors for getting to this stage with such an unpopular transfer.
In turn, Coach Walter Mazzarri reportedly threatened to resign after Sunday’s 1-0 defeat to Genoa if the club did not provide him with a new striker.
Mirko Vucinic’s agent is also in Milan, but could be sent home if Thohir pulls the plug.
Meanwhile, tension is growing in Corso Vittorio Emanuele, as Inter's Curva Nord hard-line ultras have called a protest in the street outside the HQ.
