Birmingham City boss Alex McLeish was delighted with Nikola Zigic after victory over Stoke City.
Zigic's third goal in three games earned Blues a last-gasp victory over Stoke at St Andrew's.
McLeish said: "Ziggy has become a fixture in the team as he's become more aggressive. We know he's capable of finishing.
"If we get that type of delivery to him in the box, there's not a lot of defenders who can live with a guy that size.
"When I saw the goal again, it was amazing to see him towering over John Carew, who is a giant himself.
"That is what the big fella is capable of. He was more aggressive in the second half than he was in the first, when I thought Stoke bullied us a little bit.
"But in the second we were much more enterprising."
