Chelsea, since the departure of Jose Mourinho, in their last 10 Premier games, have won five and drawn five scoring 20 and conceding 10. They have also climbed the table up to 10th place with 40 points, 10 behind Manchester City in the 4th.
On the contrary Paris Saint Germain have had a walk in the park this season. The French champions currently stay on the top of the Ligue 1 with 74 points, 23 clear of second place Monaco. PSG have lost just once in 29 games in the league. PSG are for sure an exceptional team, and they are now looked upon with scare by an incredibly weak league.
Chelsea can take breathe and hope from their previous record against PSG, given that often the team with the advantage from the first leg has failed to progress to the next stage. In the 2013/14 season PSG beat Chelsea 3-1 in France before a late Demba Ba striker sealed a 2-0 win for Chelsea. The next season, Chelsea left France with the advantage after a 1-1 draw but they were then eliminated after a 2-2 draw in London. Then Chelsea can be quietly confident ahead the match of Wednesday.
