Strachan eyes further improvement
He lifted the trophy after his side's 1-1 draw with Hibernian at Parkhead, with Maciej Zurawski cancelling out Steven Fletcher's opener.
But Strachan believes Hearts, Rangers and Hibernian will all get better which is why his squad must improve and get stronger for next time. He said: "I already know that we need to improve in this league alone because Hearts and Rangers are getting stronger, using money and when Hibs get their players back they will also be stronger.
