Mick McCarthy admitted Fulham were 'streets ahead' of his Ipswich side after the whites claimed a 2-0 win at Portman Road.
Despite opening with four back-to-back wins, the Tractor Boys were thoroughly outclassed by a rampant Fulham line-up.
Ryan Fredericks went surging down the right and his cross found the unmarked Kebano, who duly headed past Bartosz Bialkowski in minute 35.
Fonte hit the post in the first half, before scoring in the second.
Kebano almost had a brace as Bialkowski did well to save after the scorer turned his man to fire away his shot, but the rebound fell straight for Fonte to smash home the rebound in the 51st minute.
A dejected McCarthy quipped: "Call the police because there's just been a murder.
"Sometimes you just have to take your hat off to your opposition.
"They were streets ahead of us. They absolutely bashed us up with and without the ball.
"Sometimes you just can't get near the other team and that was the case.
"We tried putting round pegs in square holes. We had players playing out of position due to injury and I didn't think it was right to go negative.
"There's no need to panic. We've had four good results without all of our squad available.
"You've got to remember that it's just one game, one result. We've won our other four league games.
"We've got some time off now to reflect on what has been a really good start to the season for us."
