Borussia Dortmund were left fuming over a penalty decision in Tuesday's Champions League Round-of-16 first leg that earned hosts PSV Eindhoven a 1-1 draw.

Donyell Malen had scored a superb goal for the visitors against his former side before Eindhoven's Luuk de Jong converted the spot kick in the 56th minute at the Philips Stadion.

"Zero percent penalty, zero," Dortmund defender Mats Hummels said of his challenge on Malik Tillman.

"I go in for the tackle, I clearly get to the ball first, I change its course and then I make minimal contact. But this is football, I am sorry, zero penalty.

"Tillman was cracking up laughing, (Eindhoven winger Johan) Bakayoko also cracked up laughing, they all looked at me, grinning for several minutes," Hummels added.

The Dortmund defender got a touch on the ball before making contact with German-born US international Tillman but a VAR review confirmed the on-field decision by referee Srdjan Jovanovic, much to the visitors’ dismay.

"That is the second ridiculous penalty awarded against us in the Champions League after the (group game) at Paris Saint-Germain. I don't understand the referees at the moment," Hummels said.

Dortmund lost 2-0 in Paris in September with Kylian Mbappe scoring from the spot following a hand ball incident.

"Penalties are being awarded for situations that are not even fouls when they happen in midfield," Hummels added. "No defender in the world would award this penalty."

For coach Edin Terzic, the only thing to do was to move on. "We cannot change it, it's part of the game," he added.
