When Sebastien Haller first entered the pitch for his West Ham United debut against Manchester City, he looked like a man filled with self-confidence.

Despite hardly getting the ball, his only shot was an acrobatic effort that showed a willingness to try something outside of the ordinary.

There was also the streak of arrogance a top striker needs that was displayed in the Frenchman’s celebrations when he scored his brace against Watford, as well as his other two goals in a West Ham shirt.

However, he has now gone five games without scoring a single goal and looks like a man stripped of his confidence, as was on display against Tottenham Hotspur.

One specific moment that would show this came in the first half, when Felipe Anderson was sprinting forward with the ball and got himself into the box.

The Brazilian attempted a pass to the striker that went behind him, but rather than making a convincing effort to get the ball under control, Haller helplessly dangled out a leg as it rolled past him.

Throughout the game, he attempted five shots, but only one of them went on target, with it saying a lot that Michail Antonio managed two shots on target and a goal, as he buzzed about the pitch upon his return.

Haller has spent plenty of time isolated in the West Ham team this season and it seems as though it is now having an impact on his confidence and performances, which is definitely a concerning sign.

In other news, Manuel Pellegrini seems to be losing faith in a big-name West Ham man.
