Towering striker Nikola Zigic hopes to use his midweek derby winner as a turning point in his Birmingham career and win over sceptical supporters.
And the Serbian international, who was called up for national service before his football career took off, will look to the mental toughness gained from his Army stint to get fans behind him.
Just two league goals since his £6million switch from Valencia mean the 6ft 8in star has failed to win over the majority of the St Andrews crowd.
But he wants to kick on after his Carling Cup winner against fierce rivals Aston Villa and get supporters on his side by producing more of the same.
Zigic, 30, told The Guardian: "The expectation is one of the biggest problems that a new player faces.
"But I don't have a problem if a small section of the crowd doesn't think I'm cutting it.
"I will do my best to get those fans on side as well."
Determined Zigic insists the flak does not faze him after his character building national service spell and the jokes he received as a teenager because of his height.
He said: "I enjoyed national service.
"It's something we all have to do and I made the most of it.
"It did a lot for me and the discipline aspect was excellent."
Zigic, the tallest player in the Premier League, added: "There was a lot of mickey-taking and people did have a good laugh at my height.
"But it certainly never bothered me and it made me more determined to prove to them that I was going to play at the highest level.
"If anything all the mickey-taking inspired me to get to where I am now."
