2. Obafemi Martins (£10million)
Joe Giddens/EMPICS SportThey'll be a lot of debate about this one, and in truth it could be argued that he was a good signing, but Obafemi Martins makes the list because he wasn't nearly consistent enough in a Newcastle shirt to be worth £10million, or to be worthy of donning the number 9 shirt, which the Nigerian did for three seasons. If wearing that shirt wasn't already enough, then the fact that he was following Alan Shearer meant that the pressure on him was all the more unrelenting, but also the fall of failure was from a greater height. So in that respect, Martins didn't do so badly for Newcastle having not been ridiculed for his career on Tyneside after moving to the club from Inter in 2006. The problem Martins had was that his lack of work ethic and tendency to go missing in certain games meant that he didn't receive the level of adulation that was usually customary with the number on his back. His moments were relatively few, quite far between, but often incredibly spectacular, and in terms of entertainment, Martins was at the right club and playing in front of the right fans. He was a walking jack-in-the-box, he did the unexpected, the unpredictable, it's just that even he couldn't be sure what he was going to do. Obafemi Martins was a showman, an enigmatic and flamboyant man who loved to shock, a scorer of great goals but not a great goalscorer, and you just don't pay £10million for that.
