Ludogorets come after a win in the Bulgarian Cup, which means they will play in the final in May. Of course, they will be boosted by this fact, but still there is plenty to play for in the league, as the team is only 6 poinst from 1st place, has a direct match with the team above them and title-race is far from over. All in all, visitors will do everything they can to win this game.
For Minyor the situation can be called crazy. They team is in a good form, managed to get a draw vs the champions Litex. In fact, the team was leading 0:2 but with the help of the referee Litex got to the draw - penalty in the 94th minute. The board of Minyor is angry with the FA and their owner stated that the team will play with U19 squad as a protest.
Given these circumstances this should be a clear away win with bookies already dropping the game off. Anyway, I would still have gone for an away with even if the situation is different, as Ludogorets is clearly the better team.
