When Bukayo Saka got in behind the Wolves defence after just a matter of minutes on Tuesday evening, it looked for all the world as though the Old Gold were going to slip to another defeat.
However, the teenager’s effort struck the post, an opportunity that rather set the tone for a night of bad fortune for Arsenal.
Twice they had a player sent off as Mikel Arteta was left to bemoan the discipline of his players and the officiating on show.
Yet, despite everything that was going on, Wolves kept their cool and managed to put an end to one of Nuno Santo’s toughest runs in the Molineux dugout. This was just a fourth win in their last 14 matches in all competitions and it came against a side who had conceded only once since Boxing Day.
The form table dictated Arsenal should have claimed all three points, but it was Wolves who ran away with the victory courtesy of goals from Ruben Neves and Joao Moutinho.
Though, as vibrant as Wolves were offensively, their backline appeared to be in diabolical shape once again. They have kept just one clean sheet in the league since October and it was no surprise judging by the woeful defending from Nelson Semedo.
The Portuguese was given an early sighter in the opening few minutes of the match when Cedric danced forward from left-back and beat the right-back with a lovely piece of trickery on the edge of the area.
That set the tone for a difficult night for Semedo, someone who was at fault for Arsenal’s goal. In much the same manner as Cedric, Nicolas Pepe darted forward down the left and beat the full-back all too easily.
His attempt at winning the ball from the Ivorian was nothing short of embarrassing and Wolves deserved to concede.
During the course of the game, the Portugal international lost 66% of his duels and also surrendered possession on 14 occasions. For context, only Adama Traore and Pedro Neto lost it more, with Semedo really struggling to match up to Pepe's strength and intensity in pressing him whenever he had the ball.
It was a dismal showing from the former Barcelona man, but we shouldn’t be surprised. After all, Semedo has continued to let Nuno down since his move from Spain last summer.
Offensively, he is a ball of energy, but when presented with one-on-one situations defensively, he is abject. That was evident against Everton a few weeks ago when Semedo was left vulnerable down the right once again.
He didn’t get tight enough to Lucas Digne who was able to lay the ball on a plate for the Toffees’ first goal but he didn’t learn from it. The rampaging French left-back was able to supply as many as six crosses from Semedo’s side of the pitch.
Nuno clearly has a problem at the moment, and it’s one that could cost him nearly £37m. That sort of price tag would usually make someone undroppable. That shouldn’t be the case with Semedo however, who is still letting his manager and teammates down.
