West Ham United's Europa Conference League campaign kicked off with a win on Thursday night as they beat FCSB 3-1 at the London Stadium, although Gianluca Scamacca disappointed with his performance.

The Hammers found themselves 1-0 down at half-time as the Romanian visitors were well on top and deservedly took the lead through Andrei Cordea shortly after the half-hour mark.

However, David Moyes' side reacted well and dominated proceedings in the second half, with Jarrod Bowen equalising from the penalty spot before Emerson Palmeri completed the turnaround five minutes later.

Michail Antonio rounded off the victory in the final minutes with a great run and finish to ensure that the Hammers wouldn't join the likes of Chelsea, Liverpool and Manchester United as surprise English losers in their first European group stage fixture of the season.

Although Moyes will be delighted at the comeback win, he may be concerned with the first-half performance, especially that of Scamacca, who was hooked at half-time with Antonio coming on and making a huge difference up top as he earned an 8.6/10 rating from SofaScore.

As per SofaScore, the summer signing from Sassuolo earned a 6.7/10 rating for his display, with only Vladimir Coufal, Lucas Paqueta and Said Benrahama rated lower of the West Ham players to feature.

Scamacca had 18 touches of the ball and contribute just six passes during the match, with both of those figures lower than Hammers goalkeeper Alphonse Areola, which emphasises just how anonymous the Italian was last night.

It was also lower than his season average in the Premier League of 7.8 passes, despite him featuring for just 148 minutes across four games at an average of 37 minutes per match, which again goes to show how disappointing he was against FCSB.

He also looked like he was trying too hard to score on Thursday night, as he took five shots in total, four of which were off target and one of which was blocked, so it is disappointing that he couldn't even register a shot on target.

The 23-year-old also won just one of his five duels in the game and failed to complete a single dribble, as the FCSB defenders well and truly got the better of him.

Considering that Scamacca will be facing far more renowned defenders week in, week out in the Premier League, Moyes will surely be concerned with the way he played, especially as Antonio came on and turned the game around.

The summer signing was expected to compete with the Jamaican this season, perhaps with the view of taking over the role of West Ham's chief centre-forward as the 32-year-old approaches the end of his career, but Thursday night's showing emphasises that Scamacca has a lot of improving to do if he wants to be starting regularly ahead of Antonio this term.
