Ian Maatsen sends a pointed message to parent club Chelsea after scoring a crucial goal in Borussia Dortmund’s Champions League quarter-final win over Atletico Madrid.

Ian Maatsen sent a not-so-subtle message to Chelsea after scoring his first Champions League goal to help Borussia Dortmund reach the semi-finals for the first time in over a decade.

Maatsen was playing in the Championship with Burnley a year ago and traveled to Chelsea convinced he would have the opportunity to prove his quality for the Blues this season.

Forgotten by Mauricio Pochettino and loaned to Dortmund, Maatsen was a revelation in Germany, capping his “incredible” evening by reaching a Champions League semi-final.

“It’s such an amazing feeling, you know?” Maatsen told CBS.

“I’ve dreamed of this since I was a child, especially scoring my first goal in the Champions League. I’m so happy I can’t even describe it.

Dortmund qualified for the semi-finals, to the delight of Maatsen, on loan from Chelsea.

Maatsen sent a message to his parent club after the match following the lack of opportunities under Mauricio Pochettino earlier this season.

Asked if he ever saw himself producing big moments on the biggest stage after being shunned at Chelsea, Maatsen told Thierry Henry he never lost confidence in himself.

“I always believed I could play for Chelsea, but unfortunately it didn’t work out,” he explained.

“Now that I’m here, I’m very grateful for this opportunity. I am very proud of myself. I continued to believe in myself and came here to play at the highest level. Today I think I had a very good performance.

Maatsen scored the second of Dortmund’s four goals on the night as they beat an experienced Atletico Madrid side to reach the last four for the first time since 2012-13.

The left-back’s strike was a rocket, low into the far corner after some clever build-up play, and although it caught Atletico goalkeeper Jan Oblak by surprise, it was no fluke.

“These opportunities don’t come up often for full-backs and I’ve been practicing in training,” he said.

“I had a good touch in the box and saw the goal and put it in the net as hard as I could. Today it paid off.

In front of a crowd of 81,000, Dortmund looked as energetic at the final whistle as they did at the first, and that was down to their famous Yellow Wall, Maatsen said.

“This Yellow Wall is crazy. You felt the energy from the fans and you feel such a buzz. You feel it so much in your heart. It goes through your whole body. Big fans. I can’t describe it.
