Dubravka's arrival on loan in January was one of the catalysts for the Magpies' remarkable run of form that saw them move away from the bottom three and finish the campaign in the top-half.
Unsurprisingly, Newcastle decided to make the deal permanent in the summer, with Sky Sports reporting that the move cost them £4 million. And based on some of his performances for the club, Benitez may struggle to think of there being too many occasions where he has spent £4 million more wisely.
But unfortunately for Benitez, the brilliance of that deal could arguably be something that counts against him in the winter window when he will be desperately hoping for some serious backing in the transfer market.
Benitez has clearly not been able to make the waves in the windows that he would have liked to have made since moving to St James' Park. And the impressive deals for the likes of Dubravka and Federico Fernandez highlight that there are some gems on the market available for bargain prices.
Unfortunately, some of the club's other signings highlight that the likes of Dubravka and Fernandez are more like the exceptions to the rule when it comes to looking for bargains, and the expectation must not be for Benitez to produce more rabbits out of the hat.
It is not clear what Benitez will be working with in January, but it would be understandable if he had some fear that his cluster of brilliantly inspired moves could now count against him somewhat when his budget is decided.
