It was an unhappy return for Jose Mourinho as Chelsea slumped to a disappointing 2-1 defeat to FC Porto in Portugal on Tuesday night.
The hosts started well and eventually opened the scoring just before half time when Andre was on hand to fire home after Begovic has saved Brahimi’s initial effort.
Chelsea managed to get themselves level on the stroke of half-time when Willian curled home a superb free-kick to make it 1-1 at the break.
However, Porto retook the lead in the 51st minute when Maicon got in front of a sleeping Ramires to head home a corner at the near post for 2-1.
Costa almost made it 2-2 minutes later but his curling effort came back off the bar and it was the closest Chelsea came to finding an equaliser as they crashed to a 2-1 defeat.
The Blues now sit third in Group G ahead of their double-header against Dynamo Kiev.
