"This was a vital win for us, and of course I’m delighted." Redknapp told BBC Sport.
However Redknapp's thoughts were with Hreidarsson, who needed oxygen before being stretchered off with an achilles injury.
“The injury to Hermann Hreidarsson has put a real dampener on things," said Redknapp, who worked with the Icelandic international at Portsmouth" He's one of the best lads and professionals I've ever come across and his looks a real serious injury.
"All the players said they heard his Achilles snap like a gunshot. I really feel for him and, of course, for Portsmouth.”
