Manuel Lanzini is currently one of West Ham's longest-serving players and at just 28 years of age, he should be in the peak of his career.

But things haven't gone completely to plan for the Argentine attacking midfielder as he struggles for regular game time under David Moyes at the London Stadium.

As a direct consequence, the 5 foot 6 maestro has seen his transfer value suffer for it.

Lanzini hit a career-high worth of £18m in May 2018 and it remained at that level for nearly 18 months but with the return of the Scotsman to the dugout in east London, it has since regressed at an alarming rate.

As per Transfermarkt, his value now sits at just £9m, a decrease of 50% from over three years ago, merely highlighting the fact that he's either not delivered on the pitch consistently or the fact that he's just not been given a chance.

Either way, it should be a massive cause for concern for both the player and the club.

Lanzini should be hitting the best form of his career around about now, but with only 233 minutes of action this season and only five league starts last term, it's evident that he's hugely out-of-favour at the Hammers.

It comes with knock-non consequences - He isn't getting picked for his national side. He isn't delivering on the pitch. And the club will struggle to garner substantial funds should they ever look to sell him.

According to the Evening Standard's Jack Rosser, the £9m-rated midfielder was one of the players that the Irons were prepared to sell for the right price this summer. He told Football FanCast:

"Lanzini is another one who could potentially move on and free up some wages, although Moyes did really like him. Lanzini is an option that if a bid comes in, they would be happy to let him go."

In recent times, Lanzini has been lambasted for his performances, whenever he has been given that opportunity. For example, The Athletic's Roshane Thomas claimed that he has been "too anonymous" for large parts of his Hammers career, whilst The West Ham Way's Dave Walker believes he's "completely ineffective" sometimes.

He is also among the club's highest-earners, raking in a reported £70k-per-week, which is more than the likes of Declan Rice (£60k-per-week), club captain Mark Noble (£50k-per-week) and Vladimir Coufal (£30k-per-week).

That's another factor that may make it hard to shift him on.

Lanzini is now even further behind in the pecking order, following the arrival of Nikola Vlasic this summer, so it could be time to move him on in the winter window, though GSB will be fuming that they won't be able to get as much as they once could have done, going by the above evidence.
