Stoke, who slipped to a 2-0 defeat at Manchester City on Boxing Day, have struggled since the start of the month and have managed to pick just one point.
Despite the poor run, Pulis is not too concerned and is now targeting a crucial run of games, starting with Birmingham tomorrow.
"We have had a tough run of games," Pulis said. "Arsenal, Aston Villa and Manchester City all away from home, with just one match at home in the middle is very difficult.
"But, as a Premier League club you just have to accept there will be a run of games where it is going to be difficult to pick points up. Now we have a run of home matches, which are going to be crucial."
He has also vowed to make changes ahead of the game in an attempt to freshen things up. "We need some fresh legs," Pulis added. "Two tough matches in 48 hours is a big ask for anyone."
