Portsmouth manager Harry Redknapp hailed the progress his side have made after their victory over Birmingham.
Goals from Sulley Muntari and Niko Kranjcar secured all three points for Pompey, moving them up to fifth in the table.
Redknapp insists his team is getting stronger each season and praised his defence of Sylvain Distin and Sol Campbell in particular.
"We're stronger than we were last year, and the year before when I took over a poor team," he said. "It's about good players. There's no other secret.
"We've got people who play well away from home and the best keeper in the country, so we're very difficult to break down to start with.
"And obviously we're scoring goals as well which is good."
Kranjcar scored a brilliant free kick into the second half to secure the win for Portsmouth and Redknapp is not surprised at the Croatian's ability.
"He's got great ability, great quality, a real class player. He does that in training regularly.
"He scored one like that against Fulham last season, in open play. He's a real threat whenever he gets the ball in that position."
But Redknapp insists that his team can still make improvements particularly in midfield where he feels they lost possession too easily.
He added: "I thought we give the ball away. We had spells when we should have kept the ball better.
"We were careless with our passing and that was a bit frustrating at times. I thought we could have dominated in the middle of the park.
"I thought we gave it away too easy at times and we invited them back onto us again.
"No one can fault their attitude today, they worked hard for Eric Black. But it was another great result for us."
