Magpies boss Rafa Benitez will surely be looking to bolster his ranks at St James' Park this month, with his side far from safe in their fight against relegation, with just two points currently separating them from the drop zone.
One area where the Spaniard undoubtedly needs to strengthen is his goalkeeping department, with both Karl Darlow and Rob Elliot arguably not good enough for the Premier League.
The latter is also out injured now, so an addition of a top-class stopper will surely feature highly on Benitez's wish-list.
If Benitez does manage to pull off a loan deal for the England international though, what a sensational piece of business it could turn out to be for the Toon.
Hart lost his place to Adrian in the West Ham goal last month, but he still has a lot to offer at the very highest level.
He is one of the division's loudest communicators - something that Newcastle are desperately bereft of in their back-line, and he would bring much organisation and solidarity to their defensive setup.
Hart will be desperate for regular action during the second half of the Premier League campaign, what with the 2018 World Cup on the horizon, and he would surely jump at the chance to move to St James' Park, if he was guaranteed to play week-in week-out.
And it could be the ideal solution for all parties concerned.
