"Three games after I'd joined, the keeper told the Press we were losing because the midfield was weak. I was the new player in the midfield so of course the criticism was directed at me, not the German players.
"A few weeks later I had an argument with the keeper. We had to be pulled apart in the dressing room.
"After six months I told the sports director 'I'm not welcome here so I want to go'.
"But Dortmund couldn't find a replacement so I stayed another six months and probably played the best football of my career after Thomas Doll took over as coach. Then at the end of the season, I got a call from my agent telling me that I was going for a medical at Everton.
"It was completely out of the blue and I knew nothing about Everton. I had to go on to the internet to find out about them. When I discovered they were a famous club who had qualified for the Champions League the previous year I told my agent I'm ready to go. I didn't even say goodbye to my team-mates at Dortmund.
"I was welcomed and accepted by everyone at Everton from my very first day. Now I want to pay back that friendship. We've got two more league games to play before the FA Cup final and the manager won't let us ease up because we want to overtake Aston Villa for fifth place.
"We're a massive club with a great history but now we want to achieve some things in the modern era.
"It's not often that you get to a Cup final when you play for Everton and that will motivate us even more. Our hunger is the key."
