Ireland sometimes finds it difficult to recover from bad results because he takes his job so seriously.
He told the Daily Mail: "I'm one of these players who live inside my head quite a lot. Certain things don't go my way and I really start thinking about situations too much.
"When we drew with Burnley everyone was devastated. Some people hold on to things a lot longer than others and I'm one of those. Maybe it's one of my downfalls. The best thing is to move on but I don't. It's something I have to get out of my system because if I hold on to things too long, it's not good.
"I guess I'm a bit grumpy and snappy with my family and that's a bit unfair because, after I've finished my job, I should leave what happens behind.
"The more experience you get, the better you get. But it's a big stage and we are trying to do something here which is massive so you have to take it seriously."
