West Ham’s front three clicked into gear in the past month but the defeat against Brighton revealed a problem.

As the game started getting away from Manuel Pellegrini’s men, the Chilean was looking for something different to change the game.

Robert Snodgrass, Michail Antonio and Lucas Perez were sent on but to little effect. The absence of Chicharito was keenly felt, but he is also yet to impress in a Hammers shirt.

So, Pellegrini needs a plan B and some more potent attackers? Step forward, Grady Diangana. The young forward marked his debut against Macclesfield last month with a double, and followed it up with a brief Premier League bow against Manchester United.

But what do we know about Diangana? And how good could he prove to be? We’ve taken a closer look.

What do we know already?

The Hammers’ number 45 was born in DR Congo, but moved to the UK when he was four. From there, he has progressed through the club’s youth academy.

He joined the club aged 12, originally as a striker before being moved into an advanced midfield role. In June this year, he signed a new two-year deal; showing how highly-rated he was before he even made a first-team appearance.

He prefers to play on the right, but can play across the front-line. The Macclesfield brace showed his eye for goal, but citing Ronaldinho as an influence shows how keen he is to entertain also.

How good can he become?

When any young player breaks into the first team, it is easy to summise that the sky is the limit.

While Diangana looks a talent, he doesn’t appear outrageously good. However, he is mature for his age, making good runs and focusing on being efficient.

Getting on the scoresheet also shows impressive ruthlessness, which perhaps comes from that initial deployment as a striker.

The Hammers need an effective, nippy Plan B, and if he can prove to be that, Diangana may just find himself motoring ahead of a few experienced names in the queue.
