Jose Mourinho can often be seen screaming at his team from the sidelines during games, however during Chelsea's pre-season tour in Canada he seemed keen to show off his light-hearted side.
The Special One was able to guide his team to the Premier League title in his second season back at the club last time round, while the also scooped the Capital One Cup.
The Blues would have struggled to pull off those feats without a strong team-bond - and that was something Mourinho was keen to work on as they prepare for the upcoming campaign.

The former Real Madrid boss got a team together, including skipper John Terry, and told them they would have to, somewhat bizarrely, line up and pretend they were on an aeroplane after making them sit in formation and put their hands on imaginary controls.
The bemused team then went through the motions of steering the "plane" - only for Mourinho to give the signal for a bucket if ice water to be poured over the unsuspecting group.
Not exactly conventional but who are we to argue with a man who has won three Premier League titles and the Champions League twice, right?
