The Potters head into Saturday's Barclays Premier League lunchtime clash at Fulham with a record which shows six defeats, six draws and only one victory from their 13 top-flight fixtures on the road.
Pulis believes this season his side have put in some of the best away displays since gaining promotion to the division in 2008.
"I think we have played better away from home this year than we have in all the previous years we have been in the Premier League, and we just haven't had the results," Pulis said.
"It is something that does concern you. We have a smashing group of lads who work really, really hard and we just need a little bit of luck as much as anything else.
"Away from home this year I think we have looked a lot more solid, even against the bigger clubs.
"We have gone to Arsenal (their last away game, on February 2) and two or three years ago we would be living on a prayer.
"This year when we went there, we were beaten by a deflected free-kick (in a 1-0 defeat).
"I personally think we played really well and didn't deserve to lose that game. But we haven't had the breaks and you need them, especially away from home."
