Chelsea will look to take advantage of home advantage in the first leg and seize the initiative in this League Cup semi final. The Blues haven't beaten Arsenal in their last four encounters but haven't lost at home to the Gunners since October 2011.
Arsene Wenger has only lost more games against Manchester United (26) than he has versus Chelsea (19) in his career and Arsenal are the underdogs in this semi final tie. Arsenal have struggled for consistency on their travels this season, winning just three of 12 domestic away matches thus far. They were also eliminated from the FA Cup third round by Championship strugglers Nottingham Forest on Sunday.
Arsenal played well in patches in the 2-2 draw at home to Chelsea last week, but should really had lost that match after Alvaro Morata spurned three great goalscoring chances. A trip to Stamford Bridge is always difficult and the objective for Arsenal will be to ensure they are still in the contest when they take the game back to the Emirates.
