According to a recent report in The Chronicle, the Premier League outfit are interested in signing the 22-year-old winger.
“We have talked about the Newcastle interest and there may be something there,” Sparta’s goalkeeping coach and former Newcastle star Srnicek told The Chronicle.
“Krejci is a left winger and a very, very good player… Newcastle fans would like a player like him, he is a real entertainer. Of course he is keen.
“We had a few conversations and he was excited a club like Newcastle was linked with him. I have told him all about Newcastle because it is a fantastic club to play for.”
Should Newcastle United move for Ladislav Krejci?
Krejci has been on the books of Prague his entire career and has a contract until June 2017, according to Transfermarkt.co.uk.
The Czech Republic international, who is currently playing at the European Under-21 Championships, will cost around £8 million, according to The Chronicle.
The youngster scored 11 goals in 51 games in all competitions for Prague last season and is highly rated.
However, perhaps Newcastle would be better off spending £8m on a player who has already played in the Premier League.
For the Magpies to break into the top 10 of the Premier League next season, they need players who are already established and of proven quality.
