Olympiacos head coach Takis Lemonis is confident he can still depend on Emmanuel Emnike and his team-mates to deliver results in Europe despite Wednesday's defeat to Juventus.The former Nigeria international was on parade for 88 minutes but fired blanks as Leigh Griffiths, Patrick Roberts and Scott Sinclair were on the mark to help Celtic achieve their first European away win in 17 attempts. A disappointed Lemonis in a post-match conference said: "We had the opportunity to get more from the encounter. We had just two training sessions in order to prepare and we focused on our defensive strategy and how to intercept balls and break into counters. I have mixed feelings right now, a rather bittersweet sensation. "One cannot be happy with a defeat. But we have a good squad, quality players and I feel I can convey things to them. That is the basis of our work from now on."Up next for Emenike and his troops who are still without a point in D is a home fixture against Atromitos as they hope to improve their Super League position, having gone three points behind leaders AEK Athens.
