(Reuters) - European champions Chelsea take on Premier League title holders Manchester City at Stamford Bridge on Saturday in a re-match of last season's Champions League final. When Chelsea triumphed in Porto against Pep Guardiola's team in May, the result was considered an upset with City heavily backed to win their first Champions League. They also have a 100% record against City since Tuchel took charge at Stamford Bridge in late January -- winning in the FA Cup, the Premier League and the Champions League final. City's start has seen them lose at Tottenham Hotspur, with a draw at home to Southampton last week leaving them three points off the leading trio - Chelsea, Liverpool and Manchester United. In contrast, Arsenal lost their first three games but go into the derby after morale-boosting wins against Norwich City and Burnley.
