Nathan Tella has reflected on Bayer Leverkusens hard-fought 1-1 draw against West Ham United.
The newly crowned Bundesliga champions sealed their place in the last four of the UEFA Europa League following a 3-1 aggregate scoreline.
Bayer Leverkusen struggled in the first half of the encounter but came back stronger in the second half.
Xabi Alonsos side are now unbeaten in 44 games across all competitions for Die Werkself this season.
"We knew it would be a difficult place to come. In the first half, we did not play our best football, which won us the league and got us to the position, but we knew that we had to stick to our principles," Tella told Ian Abraham after the game.
"Obviously, the manager said a bit at half-time to get us going again, and the second half was a different performance. We are able to get through, Jeremie scored the goal, and thankfully, we are through."
Leverkusen will face AS Roma in the semi-final of the Europa League.
