Flocking to Twitter, many West Ham United fans have erupted over an official club post involving new signings Alex Kral and Nikola Vlasic.

The duo, who joined West Ham on summer transfer deadline day, are yet to make their debuts for the club but come with plenty of promise.

Kral signs for the Irons on a season-long loan deal with the option to buy and featured for the Czech Republic at Euro 2020, being added to the contingent of West Ham men from that part of Europe.

Meanwhile, Vlasic in particular racked up some very impressive numbers for ex-club CSKA Moscow last year as he joins the east Londoners permanently for a reported £26.8 million fee plus an extra £7.7 million in add-ons (BBC).

Indeed, the 23-year-old averaged a head-turning four shots on goal per 90 in the Russian Premier League over 2020/2021 - far eclipsing the numbers of every West Ham player in the English top flight (WhoScored).

Now, the club have dropped an official post regarding West Ham's two deadline day signings as their shirt numbers drop on social media (Twitter).

Indeed, Kral will sport number 33 under Moyes while Vlasic gets handed the number 11 jersey in an announcement by the club.

Flocking to this news as supporters anticipate their post-international debuts for West Ham, it's safe to say there have been plenty of reactions.
