Sorensen told The Sentinel: "It is hard. It is all about decisions and, if you just get it slightly wrong, it is a goal.
"It is the same for defenders. As a striker you can gamble and try to get in, but as a defender you are a bit more cautious.
"I think that is what happened with the first goal (against Arsenal). Their keeper wasn't coming and the defenders were looking, but bang it was a goal."
