Arsenal manager identified Chelsea's main threat ahead of the first leg, but could he prove decisive in the return leg?
Eden Hazard got away from Paris Saint Germain attacker Edinson Cavani in the above image, taken from the first leg of Chelsea's Champions League quarterfinal against the Ligue 1 side last week, but could the Belgium forward force the entire PSG team to chase the tie later this evening by gaining the two-goal advantage necessary to overturn the 3-1 deficit accrued at the Parc des Princes?
Against PSG, Hazard was Chelsea's most threatening player, even though they were humbled in defeat. Highlighted as a player capable of winning the Ballon d'Or in future years by his current manager Jose Mourinho, Hazard's quick feet confounded the PSG defenders before he converted a spot kick as well as striking the post of the goal.
Before the first leg, he was even identified as Chelsea's "danger man" by a coach who will know what it's like attempting to set-up a team to counter his skills.
Arsenal boss Arsene Wenger, whose side were recently slaughted 6-0 by Chelsea, said Hazard - who was instrumental in that Blue victory - is "extremely talented… dangerous and fast," in his Eurosport blog.
The Frenchman added: "Hazard is the big danger man. He is very efficient because he can score, he can assist and because he can get his team out of pressure situations by unlocking defences, which is key in a team with fast counter attacking players."
Hazard, 23, will need to be at his assisting, goal-scoring and foul-drawing best at Stamford Bridge this evening if Chelsea are to oversee PSG and navigate a seemingly unlikely way into the Champions League semifinal.
