I think I was just so bitter over Bobby Reid signing for Cardiff I wasn't willing to give him a chance. He's been a fantastic player for us over the years. The way I saw it, we replaced a near 20 season goal striker with an unexciting winger from Derby with fans content to see him go. Was quickly proved wrong as he had a great start to his first season with us.
Also another one which I think most of us are guilty for, Lee Tomlin. I was definitely shouting for us to sign him after that loan spell.
