The Welshman remained upbeat over his side's established Premier League status, despite seeing the Potters outplayed by Champions League contenders on Tyneside
The Potters boss insisted Walters could have helped himself to a hat-trick but saw his side go down to a double from Yohan Cabaye and a Papiss Cisse strike
“I have had a look at the statistics and had some good opportunities today and Jon Walters really could have scored a hat-trick,” Pulis told reporters.
“The main difference is that they got into good goal-scoring opportunities and hit the target. We got good opportunities and never hit the target. I don’t think their keeper had a save to make.
“I am not picking on Jon. He has been fantastic for us. He is a great lad and he kept going and kept going but he had three chances by himself, never mind the rest of the team.”
Despite the comprehensive nature of the defeat, Pulis refused to be too downhearted, citing his side's rise in recent years.
“We are getting a little bit greedy,” Pulis added. “We have been in the Premier League for four years now and we are nice and comfortable with six or seven goals to go.
“We have been to three FA Cup quarter-finals and a quarter-final of the League Cup, we have been to a semi-final of the FA Cup, a final of the FA Cup and the last 32 of the Europe. It has not been a bad four years. We mustn’t get greedy.”
The Welshman also believes that Newcastle should be bullish about their prospects of bringing Champions League football to Tyneside.
“Newcastle have got lots of momentum,” he continued. “They have got goals in them. They can be very confident and assured for the last few games because I think they will score goals.”
