Vladimir Coufal put in a poor performance for West Ham against Brentford on Sunday.
And it seems as though we now have the reason as to why.
The 29-year-old has been superb for the Hammers since moving to the London Stadium from Slavia Prague this time last year.
Coufal has been an unbelievably consistent performer for West Ham. David Moyes signed him for just £5.4 million (BBC) – what outstanding value that now looks like!
Czech Republic face matches against Wales and Belarus on Friday and Monday.
As per usual, Coufal was included in the squad.
There has been a late change, however.
Vladimir Coufal poor performance now makes sense after official announcement
The West Ham right-back has been replaced in the Czech Republic squad for their upcoming games:
That goes someway to explaining why the former Slavia Prague ace was so unusually poor against Brentford on Sunday.
He clearly wasn’t 100 per cent fit. And that has now been proven after the Czech Republic football team’s official announcement on Twitter.
Perhaps two weeks off is exactly what Coufal needs. He hasn’t had a break since joining West Ham 12 months ago.
And hopefully then he will return to his best.
