Birmingham City goalkeeper Maik Taylor says Blues must become more consistent if they are to fulfil their aim of a topten finish in the Premiership this season.
Taylor conceded two penalties by ex-Birmingham striker Andy Johnson in Crystal Palace's 2-0 victory over Steve Bruce's side.
Palace have taken six points off Blues this term and on both occasions Birmingham have succumbed to defeat within days of beating Liverpool.
Taylor says it is indicative of Birmingham's inconsistency that they can beat one of the top-flight's leading sides such as Liverpool one week before losing to a relegationthreatened team like Palace the next.
The 33-year-old, an everpresent in the league this term, says the worrying trend must stop if Blues are to progress up the table.
"Inconsistency is the story of our season," said Taylor, who believed the two-week gap between the Liverpool match and Blues' visit to Palace did not help.
He said: "We played really well last week against Liverpool who are a top-class team. Against Palace we huffed and puffed without really doing much and we are disappointed after putting on such a good show against Liverpool.
"We are disappointed because we felt there was a chance to kick on and we haven't taken it.
"Palace was the type of game we felt we could get something from to get into the top ten and look forward. It wasn't meant to be but we are still in a healthy position.
"No one expected us to get the result against Liverpool and that has given us enough space not to be looking over our shoulder. We are not too far away from the top ten and hopefully we can get that consistency which has been our downfall all season."
Blues had two good opportunities to lead at Selhurst Park before Matthew Upson and Kenny Cunningham were adjudged by referee Phil Dowd to have brought down Tom Soares.
Johnson scored from the spot with his first and second attempt after being ordered to re-take a penalty because of encroachment by a team-mate. When Johnson won another penalty after the break, which he also dispatched, there was no way back for Blues.
Taylor added: "Johnson is very lively and he took his penalties well - you just haven't got time to react. He strikes it so well that, unless it hits you, you are struggling to save it.
"The two penalties were the deciding factor because I have not had a save to make. We felt the first penalty was a little harsh and it was always going to be an uphill task after that."
