England captain Alastair Cook admitted that his team had not been good enough on the tour of Sri Lanka as they slipped to a final 87-run defeat in Colombo.
Cook's tourists wrote an appropriately miserable post-script for their failed campaign, bowled out for 215 in 45.5 overs after Tillakaratne Dilshan (101) had laid the foundations for another home win to make the final series score 5-2 to Sri Lanka.
Cook has endured a "terrible" time over the past month, on the admission of England and Wales Cricket Board managing director Paul Downton, and his last attempt went unerringly to script.
And Cook admitted that his side had not shown enough quality on the tour, although he felt there were signs of hope for the World Cup in the new year.
"It's been a tough tour in terms of results, we haven't been good enough in a few areas but people have come through personally," he said.
"Obviously Joe Root has had an outstanding one-day tour, the way he's batted. The way Chris Woakes and Chris Jordan in particular bowled."
The captain's form in the one-day game has come under much scrutiny with many questioning whether he is the right man to lead his country, but Cook remains bullish.
"I haven't played as well as I'd like this tour," he said. "I'm working hard on my game, I'm as hungry as ever to score runs.
"I'm captain of my country, yes it hasn't gone well over the last 12 months with my batting in the one-day game but I would feel very wrong to walk away.
"If that decision gets taken out of my hands then I have to hold my hands up and say I haven't been good enough but until that moment I'll do what I always do.
"I'll work incredibly hard, I'm still incredibly hungry to do it."
