On the day that Andre-Villas Boas is confirmed as Tottenham's new head coach we look back on his career to date. The 34-year-old's appointment marks his return to the Premier League just four months after his departure from Chelsea, where he was sacked eight months into a three-year contract. Prior to his disappointing spell at Stamford Bridge he'd enjoyed an almost immaculate start to his career in the dugout.
