It adds up to a season of domination for English clubs in Europe, with Liverpool and Tottenham reaching the final of the Champions League this week by overturning three-goal aggregate deficits at various stages of their semifinals against Barcelona and Ajax, respectively.
Pierre-Emerick Aubameyang scored a superb hat-trick as Arsenal stormed into the Europa League final by winning 4-2 away to Valencia, progressing 7-3 on aggregate.
On what is expected to have been Hazard's last Stamford Bridge appearance in a blue shirt, the Belgian netted the decisive penalty in Chelsea's 4-3 semi-final shootout win against Eintracht Frankfurt.
Arsenal goalkeeper Petr Cech is relishing playing his former club Chelsea in the Europa League final, which could make for a "remarkable end" to his glittering career.
Emery spent four seasons as coach of Valencia, leading them to top-three finishes in La Liga in his final three campaigns, yet he never endeared himself to the club's famously demanding supporters because his side never challenged for trophies.
Sarri's Chelsea will face London rivals Arsenal in Baku on May 29, not before Sunday's Premier League finale against Leicester City and a May 15 friendly against MLS side New England Revolution in MA.
It's unlikely that Mkhitaryan would start against Chelsea anyway after Aubameyang, Lacazette and Mesut Ozil played so well against Valencia, but having him on the bench as another option is vital.
"We are through to the final and we are all happy", Aubameyang told Arsenal's website. Emery responded in his usual manner and said, "We are in this competition with that opportunity tomorrow". This will be better for us because we put a fantastic team out of the Champions League.
"We played the first final [this season] against Manchester City and lost".
"I first competed for this title here at Valencia when it was still the UEFA Cup and was a lesser title than I think it is now", he said. "We've played badly in the last month in the Premier League, so we have to be better now".
With the comebacks from Liverpool and Tottenham making us Arsenal fans more nervous that usual, perhaps we should be considering that our opponents are seeing how well Premier League teams are playing and may be anxious they could be in for a hammering?
