The Gunners need to win the Europa League should they hope to be in the Champions League next season, but Xhaka believes all of the current top six are good enough to be in Europe's premier competition.
"Every team that can get to a final is strong enough so, we know Chelsea, we play a lot against them," he said.
"Four teams in the final shows everyone what a league the Premier League is and we hope we are ready for the final.
"You should have to go for the first six from the Premier League into the Champions League, so strong is the league.
"It is only four teams, four teams in the final now and so we can be proud."
