Muntari admits rowing with Portsmouth boss Redknapp
The Ghana midfielder said: "When I was sent off against (Manchester) United, the coach asked me if I touched the guy (Michael Carrick). I told him I didn't but that was a lie because I could see in his eyes how angry he was.
"I looked in his face and I understood everything he was saying about focusing on doing it for the team. I'm trying and, hopefully, the number of cards will reduce. I see myself as both an attacking and defending player even though in Italy I was mostly a defensive midfielder. Here I want to do both - and score some goals, too. I've only got one and that was a penalty in a game we won 7-4.
"There were already some good players here when I signed and the coach has signed some more since. So I couldn't afford to wait 20 games to fit in and I think I'm there now. At the beginning, the first three games were very disappointing for me but we've won five now (in a row) and we are fifth and must aim to stay there or do even better.
"We have done better than I thought we would but now that we are fifth we have to try to stay there and maybe even improve. We want to cheer the crowd here. I have never known one like this before. They are with us wherever we go and for me it seems we have only had home games - even when we are away."
