Boo! - Watch Robbie Keane terrify his LA Galaxy coach with well-timed prank
We can only assume that team morale at table toppers LA Galaxy is high judging by the video Giovani dos Santos posted of Robbie Keane's prank on a member of the coaching team.
The reigning champions lead the way in the Western Conference of MLS and captain Keane, along with summer signing dos Santos, have been instrumental in their impressive run of results.
Off the pitch they seem to be mixing well also, though Galaxy assistant coach Jovan Kirovski will rue their camaraderie after their stunt which the former Barcelona star posted on his Instagram account.
Entitled 'Jovan doesn't get scared easily by Keane', the clip shows Kirovski get the living daylights scared out of him as Republic of Ireland's record goal scorer seizes his opportunity for a bit of mischief.
