I don't think so, the referee was being fair with that decision since he was called back by the VAR officials. Having a close look at the action, you'll see that the ball hit the lower part of balde's hand that was away from his body. It was a clear penalty and the referee showed an unbiased judgement by awarding it.
we normally see clearer scenarios of that kind, but penalties are never awarded anyway. That looked to me like a "ball-to-hand" type of play that shouldn't have been ruled for a penalty!
I think Barcelona showed fearsome dominance in the game to overturn the score sheet even after being led by 2 goals -- that doesn't happen often! We all saw that fine cross by lamine that got delivered into the net by Elgezabal, in an attempt to clear the danger.
If we are to give credit to Real Madrid as a team, but individually -- still screaming numbers no doubt, but their current form can't match with Barcelona who are strong and sharp with much promising players who are always dominating the games and winning all their matches with many goals.
