Spanish champions Real Madrid have started the defence of their UEFA Champions League (UCL) title successfully following their 3-0 away win over Celtic who are back in the group stage of the competition for the first time in five seasons.

Real Madrid are the reigning European champions after they won the Champions League title last season. The Carlo Ancelotti-led side beat Premier League heavyweights Liverpool by a lone goal in the final to win the competition last season thanks to the second half strike from Brazilian attacker Vinicius Junior.
