The midfielder helped the Magpies to an important win over West Ham.
The 23-year-old was involved in both of Steve McClaren's side's goals as they claimed an important 2-1 victory over West Ham to move out of the Premier League's relegation zone. And Sissoko believes that the England international did enough to remind him of the way Gerrard plays.
"He [Shelvey] is a really good signing for us,” Sissoko told the Chronicle.
"For me, his style is very similar to Steven Gerrard's, because he can play the long ball easily, he can get on the second balls."
Having played alongside the 35-year-old at Anfield for three years, it is perhaps no surprise that Shelvey is starting to show glimpses of quality that evoke memories of the way Gerrard used to dictate the game with showstopping passes.
It is perhaps all the more impressive given the situation that Newcastle find themselves in currently. With a relegation battle on the cards, Shelvey may well have been tempted to adopt a much safer approach to his passing - especially with the pressure of a £12m fee to contend with (via Chronicle).
However, he hinted on Saturday that he was determined to show his teammates that they can play their way out of trouble, rather than look for scrappy wins here and there.
And if he can continue to have that influence, then it is likely that many more at St James' Park will see the attributes that Gerrard was synonymous for during his peak.
