Chelsea No2 Gianfranco Zola says the Premier League has proven their strength by dominating the European competitions.

Chelsea and Arsenal will meet in the Europa League final, while Tottenham and Liverpool will clash in the Champions League final.

“It's confirmation that right now the Premier League is at a high level," Zola told Sky Sport Italia.

“It also rewards the courage, determination and confidence of two sides who never stopped believing, despite very difficult results to come back from."

Zola was asked about the influence of foreign coaches on the Premier League.

He added: “Absolutely, the coaches are important, as they are of the top level not just in Europe, but in the world. They certainly brought new ideas, new ways of playing, which united with the aggression, tempo and determination of English football, combined to create something very effective."
