Thibaut Courtois believes the exit of both Manchester clubs has opened the way for Atletico Madrid to win the Europa League.
Atletico defeated Besiktas 3-0 away from home on Thursday, sealing a 6-1 aggregate victory and booking their place in the quarter-finals of the competition.
English Premier League heavyweights Manchester United and Manchester City were eliminated by Athletic Bilbao and Sporting Lisbon respectively.
And goalkeeper Courtois believes the early exit of the Manchester teams has left the competition wide open.
Having eliminated both Lazio and Besiktas, we have proved Atletico really can go a long way in this tournament, he was quoted as saying on the UEFA website.
With the two Manchester teams out, anything is possible in this year s Europa League. All the teams left have an equal chance of winning the trophy.
In 2009/10, Atletico won the inaugural edition of the revamped Europa League, formerly the UEFA Cup, beating Fulham 2-1 after extra time in the Hamburg final.
