The lips does not leave any doubt. Roger Federer clearly said "Fu** Off" towards the umpire Fergus Murphy after the Indian Wells final lost in three sets to Juan Martin del Potro. The Swiss was angry because Mourier allowed the world No. 6 to call the Hawk-Eye Challenge late when Federer had a set point on 6-5 in the second set tie-break. After winning it, Federer let his frustration go away and wasn't that nice with the umpire.
