Manchester City boss Pep Guardiola said being forced to watch the Champions League latter stages from his sofa instead of the touchline is providing motivation to qualify for the competition next season. City bowed out at the play-off round to Real Madrid in February -- failing to reach the last 16 for the first time since the 2012-2013 season. It was also the first time in Guardiola's managerial career that he failed to reach the last 16, but he has enjoyed the spectacle this week as Arsenal, Paris Saint-Germain, Barcelona and Inter Milan booked their places in the last four.
