The 23-year old returned from a two month injury lay-off to help troubled Portsmouth reach the cup final, riffling in the second goal from the penalty spot.
"I have no idea how I managed to get through,'' Boateng admitted.”I think I just had the confidence in my head because the gaffer [Avram Grant] was behind me. He told me I could do it.
"He asked me if I was okay after 90 minutes and I said I was, so he replied: ''okay, now I want to see you do more". That's what he's like. He always wants to see more and that's what made me believe I could make it.
"It was the most important goal of my career. I have a lot of friends who will have recorded the match so I will watch it tonight and then again tomorrow, I'll never get bored of watching it go in.
"There were so many emotions that came up when I went to take that penalty that it was unbelievable. I didn't have much luck when I was at Tottenham so that also made it a little bit more special.
"It was the second best feeling of my life after my son being born. It was the perfect day for me.''
