Jordan Pickford continues to excel during his loan stint at Preston North End after helping the Championship outfit equal a club record.
The on-loan Sunderland stopper was in goal for their goalless draw with QPR at Loftus Road, a result that meant they matched a club record for consecutive clean sheets.
Highly-rated Pickford has been in goal for all six games and his form has led to interest from Spurs, Aston Villa and Manchester United, with their scouts all keeping tabs on him.
QPR, boasting the forward talent of Charlie Austin, Matt Phillips and Junior Hoilett couldn't get past Pickford & Co.
Preston boss Simon Grayson said: "As the game wore on we looked like the side who were going to nick it.
"To get six clean sheets in a row at any level is remarkable and congratulations to everybody who has been involved."
The last time Preston kept six consecutive shut-outs was in 2000.
Washington-born Pickford has thrived for Preston since joining the Lilywhites on a season-long loan in the summer, with the 21-year-old becoming Gareth Southgate’s first-choice stopper for England Under-21s.
Pickford, alongside Duncan Watmore, are in Southgate's 21-man squad for the upcoming Euro Qualifiers with Bosnia-Herzegovina and Switzerland.
Sunderland keeper Costel Pantilimon impressed in the 1-0 defeat to Southampton but he has made several high-profile errors this season, meaning there have been question marks over whether Pickford could be brought back to Wearside in January.
The Echo understands there is a small window of opportunity in January for Allardyce to recall the youngster to the Stadium of Light.
Allardyce is keeping close tabs on Pickford's progress at Preston and has tipped him to be Sunderland's number one stopper, one day.
“I think the bigger problems lie in front of the goalkeeper, not the two goalies we’ve got here in Costel and Vito (Mannone)," said Allardyce.
“But hopefully Jordan will continue to do the job and that young man will be Sunderland’s regular goalkeeper one day.
"Whether it’s under my time or not, time will tell.”
