It’s the second week of the Champions League round of 16 matches and there are some managers who could really do with a win. Namely, Andre Villas-Boas and Chelsea. His side are in crisis mode having failed to win in four league games and been taken to an FA Cup replay by Birmingham City. To say Villas-Boas needs a win is an understatement and a trip to Napoli is hardly the easiest place to get it. With the likes of Edinson Cavani, Ezequiel Lavezzi and new Chilean star Eduardo Vargas, the hosts have plenty of firepower to test a Chelsea defence that has been less than impressive this season.
