Former Tottenham Hotspur forward Garth Crooks has written on BBC Sport that Newcastle United need to sort out their defence.
“It was just as well Georginio Wijnaldum had an inspired day and scored four superb goals,” Crooks wrote on BBC Sport.
“But if McClaren or any of his staff think for one minute that Wijnaldum, or anyone else for that matter, can keep scoring goals at this rate to win games he can think again.
“Wijnaldum needs to have a quiet word with his boss and tell him to sort his defence out.”
The fact that Newcastle scored as many as six goals cannot be understated, but defensively they do need to improve.
Norwich were playing in the Championship only last season and are one of the candidates to get relegated from the Premier League at the end of the 2015-16 campaign.
Conceding two goals against the Canaries is not a good sign, and Newcastle head coach Steve McClaren needs to address this issue.
The Magpies will take on Sunderland away from home at the Stadium of Light in the Premier League on Sunday.
