The mistake Matri made, wasn't that he decided to try go round the keeper, but the direction which he chose. Matri should have gone wide on his right as it was easier to pass the goaler, and while the angle would have been narrower, he would have been past the goaler with no chance of a defender getting there. Instead, he went inside on his left, which would have made the angle much more favourable as he would have been in the centre of the goal, however, the goalkeeper was already leaning a bit more towards that side, and there was a defender (okore i believe) who was running through the middle.
So to conclude, the mistake wasn't that he tried to dribble the keeper, but rather that he chose to go round the left side rather than round the right
