Arsenal defender Vermaelen ready to face AC Milan star Ibrahimovic
Vermaelen will again look to shackle the 6ft 3in frontman, whom he went up against at close quarters as a youngster when at Ajax.
"When I was playing regularly, he had left already, but I had a lot of sessions with him when I was a young player," said the 26-year-old Belgian international.
"I know his qualities, like everybody does. He is a strong and technical player, one of their main players, it is up to us as defenders to keep him quiet tomorrow."
