Chelsea signed Emerson last January in 2018. He was signed as a backup to Marcos Alonso but has gradually taken up the first place by playing hard football.
He has now said he wants to cap his dream season by winning the Europa League.
“It’s a derby and it’s a final, so we can’t calculate this like any game that we usually play,” the left-back told his club’s official website.
“I expect an Arsenal that will be very aggressive from the beginning because they didn’t manage to get into the top four.
“We managed to get into the Champions League and to win the Europa League on top of that would make this year a dream come true. Let’s hope we can make it happen.
“For me personally it would be immensely satisfying. I played a lot of the games and to win a tournament like this makes you feel an important player.”
“I think I have managed to do really well,” the 24-year-old said.
“I have demonstrated I am mature enough to play at this level, in this type of competition.
“I played in it once when I was at Roma but we couldn’t make it past the last 16. Now we have got the chance to play the final.
“I really hope we can bring it home, for me personally, my team-mates, the club and the fans.”
