The Magpies' utility man has hailed his side's performances so far this season, after a solid start, but is aiming for consistency after some "wobbly" results in recent weeks
Alan Pardew's men surprised many last season by managing a sustained challenge for Champions League qualification, only to falter on the final day of the season and finish fifth.
Newcastle have notched up nine points from their first seven games, leaving them in 10th position and Perch, who has played in a variety of positions already this season, has admitted that more is to come from the Magpies.

"It's been a bit up and down performance-wise," he told the club's official website.
"We've pulled off some good results and had a few wobbly performances, but overall I think we can look back and say we are quite happy with what we've done so far.
"It goes without saying though that there's room for improvement and that's what we are intending to do over the next few weeks."
