Aberdeen manager Barry Robson felt his side deserved a point from their Europa Conference League opener against Eintracht Frankfurt.

Dante Polvara stunned the home fans in the Waldstadion by cancelling out an early penalty opener before the Dons succumbed to a 2-1 defeat.

The American midfielder finished off a clinical counter-attack in the 22nd minute to net his first goal for the club and the Dons looked comfortable for the majority of the first half.

The German side stepped up a gear after the break and on-loan Leeds defender Robin Koch headed what proved to be the winner in the 61st minute.

But Frankfurt had to withstand some late pressure and unmarked Aberdeen substitute Ester Sokler missed a good chance in stoppage-time when he volleyed off target from 12 yards.

Quoted on the UEFA website, Robson said: “I am happy with the way we played and the commitment we put in, but I feel we could have deserved even more, had that once chance right before full-time whistle gone in.”

However, the Dons boss was frustrated with the manner they conceded goals.

He told RedTV: “I thought tactically we were very good, we pressed the ball at the right times. We probably could have passed it a wee bit better at times but we grew into the game.

“I am frustrated we lost (goals from) a penalty and set-play.

“That’s top, top players we are playing against, they won the Europa League not long ago and Barcelona lost here not long ago, and different teams.

“The frustration for me is that’s the type of goals we lost, ones that I think could have been avoidable.

“Listen, the players have come here and performed unbelievably well.”

Polvara admitted it was a “bittersweet game”.

“We are happy about the performance but obviously not the result,” he said. “We can take the positives from this game going forward.

“Scoring that goal was a great moment, in front of 55,000 fans. I don’t quite remember how the ball got there, it went through a couple of legs I think and then I saw that it was one of the two chances we expected we’d get before the game and I grabbed it.”

Frankfurt manager Dino Toppmoller was surprised by Aberdeen’s tactics:

“We weren’t expecting them to drop this deep but ultimately that is their choice how to play and we have to deal with it,” he said. “I am pleased with us getting the three points and the mentality we displayed.”

Aberdeen stunned Eintracht Frankfurt by equalising in the Waldstadion before succumbing to a 2-1 Europa Conference League defeat.

But Frankfurt, third-favourites to win the competition behind Aston Villa and Fiorentina, had to withstand some late pressure and Aberdeen substitute Ester Sokler missed a good chance in stoppage-time.

Barry Robson’s side had only beaten Stirling Albion in their eight previous games this season and it looked like it might be a long night in Germany when Frankfurt took the lead inside 11 minutes.

Jack MacKenzie was caught out by a pass inside him and Dina Ebimbe muscled his way in front of the wing-back. The Frenchman went down amid a tangle of legs and MacKenzie was penalised. Omar Marmoush converted from the spot.

Aberdeen delighted their 2,900 travelling fans by drawing level against the side that beat Rangers in the 2021 Europa League final.

Bojan Miovski collected a loose pass just inside the Eintracht half and was joined by several team-mates in bursting forward. The lone striker played the ball out wide to Nicky Devlin whose low cross found Polvara, who took a touch six yards out and fired high into the net past two home players and the goalkeeper. It was the American’s first goal for Aberdeen.

Some Dons fans took their celebrations too far amid reports that a lit pyrotechnic was thrown into the home end. More missiles followed amid loud jeers from the Frankfurt fans, although they appeared to be plastic cups.

There was only one scare for the visitors before the break when Paxten Aaronson got in behind MacKenzie to meet a lofted pass. Kelle Roos got down well to stop the volley before the offside flag was raised but the VAR decision would have been interesting if the ball had gone in as there was very little in it.

Frankfurt’s winner came after some sustained pressure and Stefan Gartenmann cleared a header off the line just before the corner that made the difference. Koch managed to get away from his marker and guide a free header just inside the far post.

The home side continued to press and Gartenmann was perhaps fortunate to only receive a yellow card for a hefty challenge before Roos stopped a long-range strike from Hugo Larsson and Devlin produced a goal-saving challenge.

But Aberdeen came back into the game after a triple substitution in the 71st minute when Connor Barron, Jonny Hayes and Ryan Duncan came on.

Richard Jensen headed over from Duncan’s corner before Roos saved from Ansgar Knauff and Aberdeen then forced a series of set-pieces in the final third.

Their chance for a memorable night eventually fell for the unmarked Sokler but he went for power rather than accuracy with his volley and fired off target.
