Celtic, Rangers, and Hearts prepare for crucial Scottish Premiership matches

Celtic, Rangers, and Hearts face key matches this weekend in the Scottish Premiership. Celtic leads the league and hosts Ross County, while Rangers aim to build on a recent European win against St Johnstone. Hearts, struggling with four straight losses, host Aberdeen. Hearts' recent form has declined since Neil Critchley's appointment, with only one win in their last five games. Aberdeen, despite a strong start under Jimmy Thelin, have also faltered, winning just once in four matches. Celtic's Brendan Rodgers defends midfielder Arne Engels amid calls for Paulo Bernardo to start. Rangers' Philippe Clement seeks to improve domestic performance after a strong European showing, with upcoming matches against St Johnstone providing an opportunity for recovery.
