The two sides meet at the Britannia Stadium on Saturday.
The Black Cats travel to the Britannia Stadium on Saturday afternoon as they seek to secure all three points and remain outside of the bottom three.
They take on a Potters side low on confidence too, with Mark Hughes’ side having conceded four goals in each of their last three games, losing all of those games in the process.
Haugaard is one of those who has struggled, initially replacing the injured Jack Butland before being replaced by veteran Shay Given.
The latter is now injured though, meaning Haugaard should be back in on Saturday, and Allardyce admits they will look to test him.
“They’ve lost one of the best young goalies in the country in Butland,” he told the Sunderland Echo.
“He’s achieved many results for Mark this season. After your goalscorers, your goalkeeper is your most important player.”
“Obviously they’ve had a little bit of a problem there with Shay getting injured at half-time last week and Haugaard coming on. If we can test him, he might be a little bit shaky.”
Key to Sunderland testing Haugaard will be getting Jermain Defoe as many chances as possible in the game.
The striker has been in impressive form for Sunderland this season, scoring 16 goals in all competitions, 13 in the Premier League.
They will need him scoring often if they are to avoid relegation, and Stoke City could provide them with the perfect chance to add more to his tally.
