The Blues' biggest threat this season by a mile, the Spaniard simply must start if Benitez is serious about Chelsea's Europa League credentials. Too many times this term, the interim coach's superstitious devotion to squad rotation has cost the Blues dearly and with 17 goals so far this campaign, the 24-year-old is virtually guaranteed to deliver for his side.
For those of us who know little about Steaua, the first leg taught us that they are no pushovers. It also taught us that Rusescu in particular is not short of attacking ability. The 24-year-old may have only scored from the spot, but his pinpoint accuracy was only bettered by his thunderous power. With 18 league goals this term, the Romanian is clearly a threat, but with four goals in the Europa League as well, the striker is enjoying troubling Europe's best.
The Blues will be pushed by the Romanian league leaders but, after their weekend rejuvenation at Old Trafford, Benitez's side should be able to navigate this particular banana skin and progress to the quarter-finals of the competition.
