Newcastle United are currently without Tim Krul and Karl Darlow due to injury.
Newcastle have been dealt an untimely blow after losing Tim Krul to injury for the rest of the season, and all of their other options lack experience at the top level.
The Magpies brought in Karl Darlow from Nottingham Forest in the summer, but he has never played in the Premier League before, while Rob Elliot has looked vulnerable when given first-team chances before, and Freddie Woodman is still learning his trade.
And McClaren said: “There’s a couple of months before that [the January transfer window],” said McClaren. “I certainly think that by January, we’ll know [if another goalkeeper is needed].
“Before Karl Darlow got injured, there was a possibility of Rob going away on loan, but I said ‘no, we’ll keep him here’. We like him – he’s very good in training – and now he has to produce it in the games.”
With Elliot likely to start in goal, there are worries about how porous the Magpies' defence could be in their game against Norwich City at the weekend.
Krul is one of Newcastle's most reliable performers and to be without him, when confidence is so low, is a bitter blow.
McClaren's side have not been able to pick up a Premier League win all season, and Krul's injury is not going to aid them as they endeavour to turn their fortunes around.
Newcastle are already five points adrift of safety, and if they do lose to Norwich on Sunday, then the atmosphere at St. James' Park threatens to turn toxic.
