That is the opinion of former Manchester United and Tottenham forward Dimitar Berbatov.
Frank Lampard’s Blues are the favourites to come out on top at Wembley over Mikel Arteta’s men.
The Gunners have more on the line, needing to win to secure their place in the Europa League for next season.
And Berbatov insists it will be a tight affair between the two London sides, refusing to give an outright winner.
“It's really difficult to predict how the FA Cup final will go,” Berbatov told Betfair.
“Whichever team wins, it will be the coach's first major trophy. It never matters what trophy you win, it still feels amazing.
“I think the teams are evenly matched. Arsenal need to be careful here, as they are prone to mistakes at the back.
“If they have any defensive lapses, Chelsea will take advantage. You need to be greedy for trophies no matter what you have won in the past.
“It's a big mark on your CV as a manager to win the FA Cup. I'm excited to see how Arteta and Lampard approach the game.
“I want it to be a draw in 90 minutes so we can see as much football as possible! I just don't want penalties, as it's a horrible way to end a game.

“Scoring a penalty in a shootout feels great but missing is the exact opposite. I've done both.
“It's very nerve-wracking. The players are suffering, and I hate to watch it. I just hope we see a great game, I think it might finish 1-1.”
Kick off from Wembley is at 5:30pm this evening.
