The 21-year-old is developing into one of the most promising midfielders in Europe and made his debut for the Czech Republic earlier this year.
The likes of Juventus and Inter Milan are keen to snap up Jankto, who is expected to move on either this summer or after next year's World Cup.
However his agent, Beppe Riso, has now revealed his client is being monitored by Arsenal and he would prefer a move to England.
"Arsenal like him, he's a lover of English football, and he's also liked by Juve, Inter and other teams," Riso told Sportitalia.
