Glasgow (AFP) - Stefan Johansen says he is focused on firing Celtic into the Champions League after helping the Hoops to an opening day defeat of Ross County in the Scottish Premiership.The Glasgow giants got the defence of their title off to a winning start thanks to a fourth-minute penalty from Leigh Griffiths before Norwegian midfielder Johansen rifled home a second in the 35th minute.It was a far from convincing performance from the Scottish champions as they prepare to take a slender 1-0 advantage to Azerbaijan for the second leg of their Champions League third qualifying round tie against FK Qarabag on Wednesday.And Johansen admitted the Celtic players' thoughts may have been drifting towards Wednesday's crucial clash."Obviously the Champions League is such an important thing for the club and for all the players," the Norwegian international said."Some of our focus might have been on that but we wanted to be professional and go out there and get the three points.
