Here we go. To the winner, the spoils, to the loser, the rotten Europa League. (Unless Dynamo Kiev don't win against Maccabi.)
Chelsea's record in all competitions, including the Community Shield is 8-5-10. Eight wins from 23. The only way is up, right?

Just one unexpected change from Jose Mourinho, with Fabregas dropping to the bench and the usual trio of Hazard-Oscar-Willian restored. Ramires starts, as he does in most big games.
Porto meanwhile roll without a recognized center forward but plenty of pace and trickery.
COME ON, CHELSEA!
