Brendan Rodgers enjoyed a winning return as manager and David Turnbull seized his fresh start with two goals as Celtic opened the season with a home win over Ross County. Rodgers preferred Turnbull to Reo Hatate in his first competitive match and the midfielder repaid his faith with two first-half efforts either side of Kyogo Furuhashi’s goal. He revelled in playing in the advanced role in the three-man midfield ahead of Callum McGregor and Matt O’Riley. Rodgers also made a big decision in central defence as Maik Nawrocki made his debut ahead of Carl Starfelt, who came off the bench later on, probably for his last appearance. Jordan White had scored for the visitors by that stage and O’Riley restored Celtic’s three-goal cushion before James Brown’s deflected effort provided further consolation for County. Rodgers explained the departure of his centre-half. “I wanted to put Carl Starfelt on because it might be his last game here. He has been a great servant to the club. “There is interest in him and he would like to take up that possibility. We will resolve that as quick as we can.” The centre-half’s partner, Jacynta Galabadaarachchi, left Celtic for Sporting Lisbon this summer and Starfelt looks set to follow her out of Glasgow after two years at the club. Rodgers said of Turnbull, the man of the match: “I spoke to him in pre-season and told him it would be a shame if you don’t achieve what you can do at a club like this, because you have the talent, but you have to be a working talent, and you have to be able to run and be aggressive in your game. If you can do that, then your qualities will come through. The Ross County manager, Malky Mackay, bemoaned his team’s profligacy. “Our shape and system were good, our discipline were good, and we give away a stupid penalty,” he said. “Then we don’t defend a cross in the last minute of the first half and the next minute we are 3-0 down at half-time. “I know at 3-0 here that can go on to become six or seven. My challenge for them at half-time was to be brave and go and score a goal and press high. “Sometimes we were able to do it and sometimes we didn’t because we have some new players who aren’t quite there with the explanations I give them but I was really happy with how brave they were in the second half.
