The arrival of a new coach is bound to leave players feeling nervous as they risk losing their places under the new regime, although stars of Bayern Munich appear to be relaxed following the appointment of Pep Guardiola.

Guardiola officially began duties as Bayern Munich boss last week following the retirement of Jupp Heynckes and arrives at the Allianz Arena after the Bavarians claimed a memorable Treble last season.

The former Barcelona manager, however, appears to already have his players at ease, after Franck Ribery was pictured performing a practical joke on a member of Guardiola's staff during pre-season training.

Ribery was caught on camera instigating a trick on Gianni Bianchi, with the France international crouching down behind the physio before Diego Contento steps in to complete the classic gag.

To watch the japes on the Bayern training ground, take a look at the video below. And why not leave a comment to tell us about some of your favourite practical jokes.
