The defender nicknamed 'Brush' made a big splash when he arrived at Rangers and attracted a huge amount of attention from top flight Premiership clubs in his first season.
Newcastle United were the ones to snap him up, for a massive £8 million on a four-and-a-half year contract. But almost as soon as he donned a Magpies shirt his sloppy style and mistake-ridden play when under pressure showed itself.
