Douglas Costa has voiced his frustration with Shakhtar Donetsk's profligacy in Tuesday's 1-0 Champions League defeat at Manchester United.
The Ukrainians created a number of good chances at Old Trafford, yet failed to find the net as David de Gea proved to be too great an obstacle.
The 1-0 loss proved costly as Bayer Leverkusen beat Real Sociedad by the same scoreline to leapfrog Shakhtar in the table, meaning Douglas Costa and his team-mates will be playing in the Europa League after the winter break.
"Our failure to take our chances [in the first half] had a real impact on the game, because we could have scored those goals. But we lost – that's football," the Brazilian told the official Uefa website.
"We didn't expect the night to end like this, but it's a lesson for us. We are learning, and now we have to turn the page and try again next season.
"Now the Europa League: I think we've played in it once and won it [in 2009]. We will try to do that again. For us, and any other team, the Europa League is also important."
Donetsk finished third in Group A with with eight points from six games, two points behind runners-up Leverkusen.
