Shelvey joined Newcastle from Premier League rivals Swansea City last week for a transfer fee reported by The Guardian to be £12 million.
The England international midfielder made his debut for the Magpies on Saturday afternoon, as he started the Premier League encounter against West Ham United at St. James’ Park.
The 23-year-old played for the entire 90 minutes and gave a good account of himself, helping Steve McClaren’s side to a 2-1 victory.
Shelvey took four shots, had a pass accuracy of 92%, created one chance, put in one cross, attempted two dribbles, and won 60% of his tackles.
Crooks was impressed with the Englishman’s performance and has included him in his BBC Premier League Team of the Week.
However, the former Tottenham forward has suggested that Shelvey’s attitude could pose a problem for Newcastle in the long run.
“However there was also a real dark side to Shelvey's performance when he appeared to take West Ham's Enner Valencia out of the game, which suggests to me that Shelvey is prepared to do whatever it takes in order to win a football match,” Crooks has written on BBC Sport. “The only problem with tactics like that is they can win or lose you matches.”
Newcastle are 17th in the Premier League table at the moment with 21 points from 22 matches, two points above the relegation zone.
