The talkSPORT pundit shared that he thought Shelvey’s ability wasn’t questionable as the 27-year-old is able to change a game in a moment, however, did acknowledge he could be a source of frustration for fans.
Cascarino pointed out that Shelvey needed to be more consistent and suggested this was a reason why the midfielder hadn’t been a regular name on Steve Bruce’s teamsheet this season.
“He’s been there nearly four-years in January, and he is an enigma,” said Cascarino on talkSPORT (6:53am, Saturday, November 9th).
“He is a frustrating player as he has so much ability and like he showed at West Ham last week, he can change a game in a moment, he really can.
“He hardly got a game in September, gets back in and shows what he can do.
“His consistent is vital for him as to be at a club nearly four-years, and he is 27-years-old now, he’s got to be more consistent.
“No one questions his ability or anything around him, they just question his consistency.
“I think he is a massive plus for Newcastle.”
Shelvey has only played six times in the Premier League this season, with Bruce preferring to play Isaac Hayden, Sean Longstaff and even Matty Longstaff ahead of him at times. Despite his limited appearances, the 27-year-old has still managed to rack up two goals in his league outings and bizarrely, or even worryingly, is the Magpies’ current top scorer. In fact barring Yoshinori Muto, whose barely played but has got a goal to his name, Shelvey has the best goal-per-minute ratio for Bruce’s side currently as he has scored every 201 minutes (Source: BBC Sport). While these stats may be more of a damning indictment of the Magpies’ attacking options, it does show how Shelvey has the ability to be a gamechanger as it’s not unthinkable to imagine him popping up with vital goals. The midfielder has averaged 1.3 shots and 1.2 key passes per matches across his league outings, as per WhoScored, and if he could play to the best of his ability in all his outings, he could easily help the Magpies climb the table, but that’s a big if. Only time will tell if Shelvey is able to be consistent this season, however, he surely knows that Bruce will drop him if he doesn’t deliver, as the Magpies boss has already done that this season.
