The first leg of the Champions League quarter-final at the Camp Nou finished in a 1-1 draw, with Courtois producing a number of saves in the latter stages to secure his side an advantage ahead of the second leg next week.
"Atletico have a great team and their players can really do damage," Bartra told reporters. We competed against a very competitive side and we had clear chances to make it 2-1 but, because of Courtois, we're leaving with a draw.
"Even as much as they pressed and tried to take the ball off us, I believe we created the most and the clearest chances to win it."
"We'll go to the Vicente Calderon to win. If we play the same way we played on Tuesday, we'll have our chances to win at the Calderon."
The second leg will take place at the Calderon next week.
