Portsmouth boss Paul Hart won't shy away from making big calls after giving Nwankwo Kanu his chance in their victory over Everton last week.

Hart said: "If you dwell on what has happened in the past, that's when decision-making becomes difficult - it confuses the issue.

"Decisions are made game by game and we try to make decisions on the state of the game.

"Kanu was on to make that ball stick a little bit more in the central areas and to try to bring people into play. David Nugent absolutely worked his tail off and some fresh legs always helps.

"The timing of the substitution maybe distracted Everton a little bit. I'm not saying it did, but that's the chance you take."
