Hearts manager Csaba Laszlo is hoping bad-boy Marius Zaliukas returns from his latest suspension a more mature player.
The 25-year-old Lithuanian defender is yet to play for the Tynecastle outfit this season due to a four-match SPL ban.
Zaliukas is available for Sunday's trip to joint-leaders Celtic and Laszlo is pleased to have him back among his match-day squad.
However, the Hearts boss has hinted that his days at the club may be numbered unless he is able to clean up his act after being dismissed four times last season.
"This is a positive for us," he told the club's official website. "Having Marius available gives us more options, definitely.
"He is a good player but he must learn from his mistakes as he cannot give anything to the team on the pitch if he is sitting in the stands."
