Playing with only 10 players since the 43rd minute, really made it difficult for Arsenal to score a goal in this match. I think that shouldn't have happened, considering that Wolves at this moment are also not in a good trend. Thus, Arsenal should still be able to score a goal in this match but yes, because Wolves also managed to play better in the second half, it might make this match end in a 0-0 draw. Indeed, there is still enough time for them to score a goal in this match, but it seems that if Wolves can consistently put pressure and or attack, then maybe Wolves will score a goal and will make Arsenal lose at Molineux Stadium, who knows.
Arsenal finally got a goal in the 74'. Wolves got a red card in the 70' which made their defense slack and this gave Arsenal the edge. R. Calafiori got his winning goal in a crutical time. Arsenal tried to have held Wolves down with 10 men for almost 24' and when the game got normalised with equal number of players we saw Arsenal take their winning goal.
Wolves gave good pressure to Arsenal but their pressure wasn't enough for a win. If they had taken advantage of the one man down since 43' maybe they would have scored first and the game might have ended in a draw or they would have succeeded in defending their goal till the end. But Arsenal ended up outsmarting them.
