Midfielder Kingston has been linked with Portsmouth, Wigan, Bolton and West Brom, while Newcastle manager Joe Kinnear has revealed he is monitoring left-back Obua and Burnley boss Owen Coyle is a known admirer of winger Andrew Driver.
With QPR also reportedly on the trail of midfielder Bruno Aguiar, there is no shortage of speculation regarding comings and goings at Tynecastle.
But Laszlo is unfazed by the situation, telling Hearts News Today: "If the players are not doing a good job then nobody is interested in them.
"If Hearts are not in a good position in the table then there isn't interest from anyone.
"But when players play better football and the team does better then you get other clubs looking at you. That is normal in football and it doesn't bother me - it is life.
"All of a sudden, players who were maybe not known too well outside of their own clubs, start attracting interest.
"For example, the likes of Zaliukas, Berra, Wallace, Driver, they are all excellent players who are doing well for Hearts just now."
