On-loan Chelsea defender Matt Miazga says the Premier League side has been closely monitoring his progress in the Eredivisie.
The United States international defender joined Vitesse at the start of the campaign in a bid to secure regular first-team football away from the Blues.
And the 21-year-old has confirmed that the English side have been offering feedback on his displays after featuring 28 times this season for the Dutch outfit.
"At Chelsea they're keeping an eye on me," he told ELF Voetbal. "After every game, I get sent videos showing good and negative moments. They are very helpful.
"I speak with them every three weeks about my progress. The focus is to play as much as possible at Vitesse. After the season I will talk to Chelsea and my agent, and we will see what is next."
Miazga joined the Premier League leaders in 2016 on a four-and-a-half-year contract from New York Red Bulls for a reported fee of £3.5 million.
