Trialist pair Arunas Klimavicius and Graham Barrett have impressed Hearts boss Csaba Laszlo, but is still to make a decision on whether to sign the duo until the end of the season. Laszlo said: "Everybody knows we have a problem in central defence.

"We didn't get Pavol (Farkas) and now Zaliukas has a suspension problem.

"Marius was freed by Dinamo Moscow after playing 11 or 12 games for them.

"This week, I have time to decide his future. I think we need somebody until May in this position.

"I don't like to go into details, but you can see in training he is a complete player. He has positional knowledge.

"Barrett is also very interesting. This week and, maybe next week, he can stay with us and we can decide if we give him a chance for the rest of the season.

"Inverness, Hamilton: these have been hard games. I'm sure Saturday will be too."
