Chelsea defender Gary Cahill admits the final 20 minutes at Carrow Road against Norwich City were "horrible" as the Blues hung on to win 2-1.
Guus Hiddink's men needed just one minute to go ahead in the Premier League fixture when Kenedy hit a superb drive from around 20 yards out.
Norwich then looked to have been killed off on the stroke of half time when Diego Costa lifted the ball into the back of the net.
But Norwich were given hope in the 68th minute as Nathan Redmond struck to halve the deficit. The Canaries then pushed Chelsea hard, with Redmond and substitute Gary O'Neil having good chances.
Chelsea though held on, much to Cahill's delight and he was quoted as saying by the BBC after the final whistle: "It was horrible by the end. The last 15 to 20 minutes was tough.

"But in first half we were in control. In the second, it was a totally different game.
"Credit to them. It feels good to dig in and grind out the result", the England international added.
Norwich have slumped into the Premier League relegation zone following the defeat, while Chelsea have now won their last three successive league matches.
And the Blues have risen to eighth in the league standings, strengthening their hopes of making the top five.
