It is not everyday multimillion pound footballers are put through their paces in a ground where grass grows from the stands, but David Moyes' side have done just that.
That's because the Hammers have swapped their 80,000-seater London Stadium for a derelict one in Prague.
Though the Great Strahov Stadium, located in the Czech capital, is not as bad as it seems.
It was in fact once a world-beating venue housing up to 250,000 spectators back in its day and 56,000 seats, making it it larger than any current or former sports stadium - the second largest ever.

"We're absolutely thrilled to be in the final," said Hammers boss David Moyes.
"It's a big achievement for the club, but now it's about going and winning it."
The Hammers have not secured a major European trophy since defeating 1860 Munich in the final of the European Cup Winners' Cup at Wembley in 1965.
Their last major domestic trophy was the 1980 FA Cup, and Moyes will be hoping to guide his side to silverware, which would also lead to qualification for next season's Europa League group stages.
