Scottish Premiership leaders Hearts look to extend their four-point gap at the top when they host Aberdeen. The “Jam Tarts” are currently on a 19-match unbeaten run at Tynecastle in all competitions, a fortress-like record that has defined their title charge. They concede less than a goal per game on average, while Aberdeen arrives in Edinburgh having failed to win in their last several outings. Hearts have scored in 16 consecutive home league games, making them one of the most reliable attacking units in the country.
