"I told the referee he was wrong, it was a clear goal"

Hansi Flick thinks the referee was wrong to flag Robert Lewandowski offside for the goal that would have made it 1-0 in their league defeat against Real Sociedad. The Pole was parallel to Nayef Aguerd and, according to the semi-automatic detection of offside positions, the toe of his boot was in front of the defender's feet, something that did not convince the Barcelona coach.
“It certainly wasn't our day. We have to accept this result, I think they played decisively. It's clear what we saw and there are no excuses, we didn't create enough chances. We started very well with the ball. I was happy, but then we started to suffer and the goal came," he said.
“I told the referee it was a bad decision, but it's not his fault and I know that. That's all I can say. It's normal to miss Lamine. We tried, but we couldn't. I'm not sure he will be back after the international break. I hope we can find out a bit more about his condition in the next few hours,” he told reporters. In this way, he considers the defeat to be fair despite the controversy with his striker's goal.
“It's a complicated pitch, where Real presses a lot. We've had them and those chances have to be scored. We have to learn from our mistakes and continue. Real Sociedad is a team that presses very well, they don't let you play out from the back. It was very difficult for us to start the move. In the second half, we lacked clarity. We have to analyse it and keep working after the break. We're doing well and we're still in first place,” he concluded.
