Goalkeeper Alexander Schwolow says leaving Hearts has been one of the toughest decisions of his career but insists it was made for family reasons rather than football. The 34-year-old is set to make his final appearance for Hearts in Tuesday night's Champions League second qualifying round second leg before returning to Germany after deciding his family had been unable to settle in Edinburgh. The Tynecastle club trail Sturm Graz 4-0 heading into the match in Gorgie, a deficit they need to overturn to progress to the third qualifying round of Uefa's premier club competition.
