Celtic striker Callum Osmand feels he has had a decade's worth of learning experiences in a debut season marked by major highs and lows. The English forward, 20, netted for the club for the first time in November's League Cup semi-final win over Rangers but an injury picked up in his next appearance kept him out until Saturday's dramatic title-clinching victory over Hearts. Osmand's added-time goal completed Celtic's 3-1 win as they climbed above the long-time leaders on the final day of the season to become champions.
