Gordon isn't world class player or even showing signs that he could become a top quality player in the Premier League. For some reason Chelsea seem desperate to take a punt on him because he works hard and has a lot of pace. We all watch him on a weekly basis and can see him for what he is: desperately lacking in end product and full of hustle and bustle.
He could turn into a decent player with the right coaching and with better players around him, but there's a reason why almost the entire football world is gobsmacked at Chelsea throwing that money at him. I imagine if he wasn't English they wouldn't be interested in signing him. Players like him are ten a penny; the English tax has trebled his value, luckily for us.
