Celtic manager Martin O'Neill has backed striker Kasper Hogh to score 20 goals for the Glasgow club this season. The 25-year-old became Celtic's record signing when he joined from Bodo/Glimt in the summer but has only scored in one game - albeit a hattrick - at the start of the season. Fans are beginning to ask questions of the striker, who missed a decent chance when Celtic were 2-0 down in their Europa League tie in Benfica on Thursday night. He was substituted at half-time with fellow summer signing Camilo Duran moved back to his favoured position through the middle. But O'Neill, whose Celtic side host Hearts on Sunday, expects the forward to come good. "At the end of the season, I expect Kasper Hogh to score 20 goals. "He has lost a bit of confidence, we will get that back during the course of time. "We have game after game after game between now and January but he will score goals for us, there is no question about it and it is just a matter of tinkering around but that's the nature of the business."
