Soucek, along with a number of Czech celebrities including former Chelsea and Arsenal goalkeeper Petr Cech, was invited to take part in a telethon promoting the campaign, which raised a total of six million Koruna (£190,000).
The campaign is aiming to raise funds to buy medical equipment for frontline staff, with a fundraising target of 10 million Koruna (£325,000).
Much like Hammers captain Mark Noble, who gave £35,000 donation to his local borough in Basildon to help local East end people impacted by the lockdown, Soucek made his own personal donation to the cause to help his fellow countrymen.
