A worrying report has surfaced that'll surely leave West Ham United boss David Moyes worried...

What's the word?

According to The Sun's Charlie Wyett (via the Daily Mail), the Irons' new summer signing Kurt Zouma's £125k-per-week wages haven't gone down with the Scot's tight-knit group of players at Rush Green.

The 26-year-old centre-back, who has won two Premier League titles and a Champions League, joined the east London outfit in a reported £29.8m deal from Chelsea just a few days before the deadline last month.

His wages have instantly seen him become the Hammers' highest-paid player, as per Spotrac, with Andriy Yarmolenko (£115k-per-week) and Jarrod Bowen (£96k-per-week) following closely behind.

Trouble in paradise?

It's no wonder several of Moyes' current squad are upset by this development, even if a player of that calibre has fully justified such a high amount of money.

For example, in recent months, Vladimir Coufal has reportedly been left frustrated and let down with talks over a new deal, per Sky Sports.

The Czech right-back wants to remain at the club but feels the quality of his performances last season has earned a major hike on his £30k-per-week contract, rather than it being based on appearances.

Similarly, the ever-reliable ExWHUemployee recently revealed the reasons behind Declan Rice not signing an extension at the London Stadium yet. In response to the Telegraph's bombshell that the England international had rejected two new offers, the club insider said (via Hammers.News):

"The information about Rice is true. This is because the contract offers have been below what Yarmolenko is currently on, what [Javier] Hernandez was on and other well paid players. For the player to stay at the club and turn down big moves the pay needs to reflect his ability."

Therefore, this claim from The Sun could have some truth to it, particularly given Ex's previous remarks on a similar matter.

This is the last thing that Moyes will need heading back into the domestic campaign following the international break. His side have started the season in great form, going unbeaten from their three matches, having ended last term in sixth-place and earning qualification to the Europa League.

He won't want a situation brewing heading into some crucial encounters, including their first group game in Europe, so you could forgive him if he was a little concerned about the players' attitude and morale.

All in all, the squad should be delighted with the addition of Zouma as it takes them one step closer to the next level. The rest should come in due course, if the Hammers' hierarchy has any sense about them.
