Stoke City manager Tony Pulis believes the club's supporters have no reason to "moan and groan".
.
The Potters have won just once in their last 13 Premier League games and sit three points above the relegation zone.
.
But Pulis has called on Stoke's fans to get behind the team in their three remaining home games.
.
"It is important everyone recognises they have to get behind the club and get behind the team now. This is when we need them the most," Pulis said.
.
Stoke face league leaders Manchester United at the Britannia Stadium on Sunday in the first of their six remaining games this season.
.
They were booed by home fans at half-time in their 3-1 defeat by Aston Villa, a loss which heightened their relegation fears.
.
Supporters have grown frustrated this season as Stoke, who have never finished below 14th since promotion to the top flight in 2008, failed to progress up the table despite significant summer purchases. Pulis brought in Charlie Adam, Steven Nzonzi, Maurice Edu, Geoff Cameron, Michael Kightly and Michael Owen last summer.

Brek Shea and Jack Butland were also signed in January, although the latter was loaned back to Birmingham. Stoke's net spend over the last five years is reportedly close to £80m.
