Multiple reports have confirmed that Panathinaikos have made their first official bid for Stefan De Vrij by submitting a formal offer. The Inter defender has long been admired by the interested team, who see him as the perfect addition to their squad ahead of the run-in. Whether the current offer will be enough to tempt Inter to part with a prized asset remains to be seen. Newcastle, Al Hilal and Bologna are reportedly waiting in the wings. Finalising a fee and payment terms remains central to closing the transfer. Panathinaikos's back line has been a real strength this season, conceding just 1.05 goals per game (22 in 21). Stefan De Vrij would be expected to slot into that unit and hold his own in an already solid setup. Inter continue to be linked with Marco Palestra, Ivan Provedel and Curtis Jones while Panathinaikos are also rumoured to be tracking Ivan Martin.
