Soucek and Coufal were revelations for West Ham after being snapped up by David Moyes from relative obscurity.
The pair were already fixtures in the Czech Republic team but their stock rose higher with their national side too as they enjoyed a meteoric rise with West Ham.
Soucek went on to be named the Czech captain with close friend and Hammers teammate Coufal by his side as vice-captain.
The West Ham dream has become something of a nightmare for Soucek and Coufal over the last year, though.
Both are unrecognisable from the players West Ham fans quickly fell in love with.
Soucek is a shadow of the all-action midfielder who looked a genuine threat to score in every single game.
And Coufal has never been the same since a hernia and subsequent operation.
It doesn’t help that they are both trying to rediscover their best form in a West Ham side playing a system that is simply no longer effective with the club languishing in the bottom three of the fledgling Premier League table.
Their fortunes at international level have fallen off a cliff too.
Last night saw things go from bad to worse for Soucek and Coufal as the West Ham duo hit a new low.
With their club form and fortunes at rock bottom, they both played as the Czech Republic were smashed 4-0 by Portugal in the Nations League.
It takes a lot to substitute off your captain at international level.
And Soucek was hooked after 77 minutes to be replaced as skipper by Coufal.
Having failed to qualify for the World Cup, West Ham’s Czech duo must now hope they can beat Switzerland on Tuesday night or they – like Declan Rice and Jarrod Bowen with England – will be relegated from the Nations League Group A.
What the future holds for Soucek and Coufal at West Ham is unclear. Both wanted new contracts after their own amazing debut campaigns.
Neither got one and, in Soucek’s case in particular, that has led to reports of a rift between David Moyes and the midfielder.
If Moyes was hoping the international break might give some of his stars a boost in morale and confidence after West Ham’s dismal start then he will be disappointed.
