Bernd Leno's injury has changed my career. Other great goalkeepers - such as Iker Casillas - have got their big opportunities when the first-choice keeper was injured.
England has always been famous for great goalkeepers, before I came. We had good goalkeepers, but we didn't have the big world-class 'keeper, maybe.
Each of the top goalkeepers has a particular quality to teach me. I look at Diego Lopez, Iker Casillas, Victor Valdes, Gianluigi Buffon... they all have tremendous experience and ability, and have spent years proving they are the best.
My relationship with Iker Casillas is very good - he is a great companion.
There were periods when I was first-choice keeper and was starting to consolidate my position when out of the blue I got injured. It happened a few times and it really unsettled me.
Iker has never stopped being one of the best goalkeepers in the world. For me, Iker is a top goalkeeper and has never not been.
Iker Casillas is one of those keepers who always seems to be at his best in the really difficult games when he has hardly got anything to do but reacts when needed in those emergency situations.
Iker Casillas is a legend, a myth, and myths do not give up just like that.
I've got no hamstring in the middle. I'm basically running on two hamstrings on my right leg and three on the other. That injury has probably changed my whole career. I've been compromised from the age of 19.
Look at France and Didier Deschamps; he was just a guy who just did his job but he was captain of one of France's most successful teams. Then you've got Iker Casillas; he's not into PR or things like that, but he's one of the most successful captains of Spain.
Everyone knows Iker Casillas. We have all followed him being at the top level for so many years. What he has done for the national team is something impossible to equal. But I try and learn from him when we are there,and train the best I can.
I played tennis a lot when I had the skull injury. For the first two months of my preparation, it was all I could do. It is a great sport for me because it helps my hand-eye coordination, and you need quick feet, which is a good exercise for a keeper.
One of the most painful things for me was Jay Leno, Jay Leno going back on the air and saying to people that it was a choice between his writing staff and his crew, I think that really hurt a lot of show runners, because it was never a choice between our writers and our crew.
A lot of goalkeepers are naturally very vocal and outgoing so it's a natural thing for a keeper.
It was the toughest phase of my life. I suffered almost a career-ending injury. Getting through the first phase of my injury was tough.
Three or four years ago, I got really caught up in the movies people were making, the opportunities they were getting, and I was looking at them with bitterness. As soon as I decided that their career was their career and mine was mine and I would have to serve myself, my attitude changed. I'm as normal as you can be in these circumstances.
If I have got an injury, I have got an injury. Whenever I want to play for Nigeria, I must be 100 percent, I want to give everything. But if I have got an injury, I don't want to force myself, because I am going to look stupid on the pitch.
