Mikael Forssell vowed to recapture his form of two seasons ago and says that his belief had not been shaken by his penalty miss for Birmingham City in the Carling Cup clash against Norwich City.
The Finland international striker will go into the home clash with Everton tomorrow - the club who wanted to sign him in the summer - still searching for his first Premiership goal of the campaign.
Forssell had a chance to bolster his confidence in the match against the Canaries, which Birmingham won 2-1, but sent his first-half spotkick several yards wide of Robert Green's goal.
Forssell is taking his time in regaining full matchsharpness after nearly a year out of action following knee surgery.
But the £3 million summer capture from Chelsea is adamant he will eventually turn back the clock and demonstrate the finishing which brought him 19 goals when on loan during the 2003-2004 campaign.
Forssell said: "A penalty miss is horrible for any player - but I know I am a big player and I will bounce back. My general play is getting better. I am starting to feel sharper and quicker.
"I do need a goal. Obviously I am not 100 per cent fit, but the only way to achieve that is by working hard. The best thing is that the gaffer trusts in me and I am in the best situation I can be in at the moment.
"I know the goals will come. I am getting the ball around the box and it is coming for me. I am starting to understand Emile Heskey more, getting onto his flickons and my general play is improving.
"I am feeling fitter. I can play longer in games. I have to see the Norwich game as a positive thing - apart from the missed penalty."
Forssell admitted he would gain extra satisfaction from scoring against Everton after suggestions he had failed a medical with the Goodison Park outfit on his knee before joining Blues.
He said: "There will be extra satisfaction if I score on Saturday. That would be great. It is not going to be an easy game. Both of us are fighting for our lives but the win over Norwich and another on Saturday could turn the season around."
Forssell insisted: "I did not fail a medical at Everton. It's not true. They were very interested in signing me, I had talks with them and I decided to come to Blues which was a great move.
"I thought this was a better place for me to come back from my injury and this is the team that I wanted to play for. I had a great time here and I'm having a great time now. It is a great place to play my football.
"When Everton wanted to sign me, there was no doubt in my mind that the knee was structurally fine. I was out for a year and then the rumours started but I have no grudge against Everton or anyone."
