Hearts full-back Danny Grainger is not surprised former club St Johnstone have started the season so well despite a number of summer changes.
Saints lost Grainger and Michael Duberry from their regular back four but have continued their impressive defensive record from last season, having yet to concede a goal away from home.
The Perth side only scored 23 goals in the Clydesdale Bank Premier League last term, less than relegated Hamilton, but the arrival of Francisco Sandaza has given them a lift with the Spaniard already on six goals. So Grainger expects a tough afternoon when Hearts visit McDiarmid Park.
"You don't get any easy games in the SPL," Grainger said. "Going back to McDiarmid will be difficult, they seem to have solved their goalscoring problems with Sandaza and Cillian Sheridan.
"There were players there when I was there who were more than capable of filling in when the likes of me and Doobs were going to leave.
"You have Dave Mackay, Alan Maybury and Steven Anderson who were there last year, who played a massive part when we went on a good run."
