Kral joined the Hammers at the start of the season, completing a Czech trio with Tomas Soucek and Vladimir Coufal at the London Stadium.
The Czech midfielder made only one appearance in the Premier League, a one-minute cameo against Watford when the Hammers were comfortably winning, and ultimately took to the pitch only six times in the past season.
The London club have the option to make his signing permanent but after the midfielder failed to break into David Moyes’ team, the Hammers will not exercise it.
Nonetheless, the midfielder wants to continue in England next season, even if it is not with the Hammers, as opposed to playing at parent club Spartak Moscow.
Kral’s contract with the Russian club expires in the summer of 2024 but it is understood that he will be allowed to leave on loan.
A number of clubs have already made contact with the representatives of the midfielder.
The midfielder will be hoping his next season in England is more fruitful than the one gone by with the Hammers and he takes to the pitch more often.
