A split second decision by Hearts manager Craig Levein may have a huge impact on one of his recent signings.
Levein substituted David Vanecek after only 32 minutes in the recent 2-1 loss to Dundee.
As reported by BBC Sport, Levein revealed that the player apologised to him after the game for his lack of fitness.
Vanecek was playing only his 2nd game for Hearts after joining from FK Teplice in January.
How Vanecek responds to Levein’s decision could make or break his Hearts career.
If he is able to cope with the criticism from his manager and knuckles down, he could prove to be a good signing for the Tynecastle side.
However, if he doesn’t respond well to Levein’s decision then his career at the club could be over already.
It is vitally important for Hearts that Vanecek is a success.
He has been brought in to help a side which started the season very well, but have since faded badly due to a series of injuries.
They still have a chance to make something of the season though.
They are only 6 points off 3rd place in the Scottish Premiership table.
They also have a very favourable Scottish Cup tie against Auchinleck Talbot.
Vanecek could well be a key man in both of those battles, and a goal in the upcoming league match against St Johnstone could be the start of that.
