German midfielder Heber trains with Hearts

German midfielder Tibor Heber will train with Hearts on a short-term basis.

The 23-year-old attacking midfielder has been playing for Bundesliga 2 side Alemannia Aachen, one of the opponents on the Edinburgh club's upcoming German tour.

Meanwhile, Jambos boss Csaba Laszlo has warned that nobody is assured of a place in his team.

"Next season will be a new team and new chances for everybody," Laszlo told Hearts News.

"At this moment everybody gets their chance and if they use it, they keep their place in the team.

"That is how football works. You give someone the opportunity and it is up to them to take it. Then we go from there."
