- Costa must be back in form
The Chelsea striker gave lots of encouragement during his last game against Porto in the Champions League. He looked like the Diego Costa of last season, running in behind defenders and creating space for his teammates. Replicating this performance will definitely make things hard for PSG who haven’t been particularly good at defending. The Blues can easily exploit their back four if Costa does what he’s supposed to. The feisty forward appears to be regaining the confidence and hunger of last season but was again worse against Leicester in the Premier League loss to Foxes. He will need to be the focal point for his team if they are to stop the roaring PSG from advancing into Quarter-Finals at the expense of the Stamford Bridge side.
